Sauces & Condiments
Martha Stewart's pesto sauce recipe transforms simple pantry staples into a vibrant, basil-infused sauce that elevates everything from pasta to sandwiches. The secret lies in balancing fresh basil, toasted nuts, and sharp Parmesan for a sauce that's bright yet rich—no bitterness here.
I've perfected this version over years of testing, ensuring it stays fresh-tasting even after refrigeration.
This recipe delivers restaurant-quality results in just 10 minutes of prep, with no special equipment beyond a food processor. The key is using high-quality olive oil and freshly grated Parmesan, which make all the difference in flavor depth.
For extra richness, I add a touch of lemon juice to brighten the sauce and prevent it from turning bitter over time.
What you'll end up with is a velvety, herb-packed sauce that clings beautifully to pasta, enhances grilled meats, or transforms simple sandwiches into gourmet meals. The texture is perfectly balanced—creamy yet light enough to drizzle without overwhelming.
It also freezes well, so you can make a big batch and have it ready for future meals.
For variations, try swapping walnuts for pine nuts or adding sun-dried tomatoes for a deeper, slightly sweet flavor profile. The possibilities are endless, but the foundation remains the same: fresh, vibrant, and always delicious. Let's get started!
Ingredients for martha stewart pesto sauce
Fresh basil and high-quality olive oil create Martha's signature vibrant, restaurant-worthy pesto sauce in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Basil Leaves 🌿 | 2 ½ cups | Packed, stems removed, vibrant green |
| Extra-Virgin Olive Oil 🫒 | 1 cup | High-quality, fruity, cold-pressed |
| Toasted Pine Nuts 🥜 | ½ cup | Lightly toasted in dry pan |
| Garlic Cloves 🧄 | 3 cloves | Peeled, roughly chopped, fresh |
| Parmesan Cheese 🧀 | ¾ cup | Freshly grated, aged 24+ months |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, seedless |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain, sea salt preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Coarsely cracked peppercorns |
The basil is non-negotiable—farmers market bunches have the most vibrant flavor, but even grocery store basil works if the leaves are bright and plump. Toasting the pine nuts in a dry pan until golden (about 3 minutes) deepens their flavor dramatically. Costco or Trader Joe's are great for bulk pine nuts at reasonable prices. For the Parmesan, always grate it fresh from a wedge—pre-grated cheese contains anti-caking agents that ruin the texture. If you can't find aged Parmigiano-Reggiano, Parmigiano-Reggiano DOP from specialty stores is the next best thing.
No pine nuts? Walnuts or raw cashews work beautifully—just toast them first. Short on basil? Spinach or arugula at half the amount adds a different but delicious twist. The olive oil should be something you'd drizzle on bread—California avocado oil or Spanish Arbequina elevate this further. If you're making a big batch, double the lemon juice to prevent bitterness. For extra richness, add 1/4 cup of heavy cream at the end, but keep it optional—Martha's classic version stays light and fresh.
This sauce keeps beautifully—cover it with a thin layer of extra-virgin olive oil before sealing to preserve color. It stays fresh for 5-7 days in the fridge, though the flavor actually improves after the first day. For long-term storage, freeze in ice cube trays—each cube makes the perfect portion for a single meal. Thaw overnight in the fridge and give it a quick pulse in the food processor to restore texture.
Why You'll Love This Recipe
- No Food Processor Needed: I’ll admit, I skipped the food processor for years—just pulse the basil, garlic, and pine nuts in a blender until it’s chunky but still vibrant. The texture’s imperfect, but that’s where the magic happens: those little flecks of garlic and toasted nuts make every bite feel special.
- Garlic-Parmesan Punch: Between us, the secret’s in the ratio—two cloves of garlic to a handful of basil, then that sharp Parmesan. The olive oil ties it all together, but honestly? The moment the toasted pine nuts hit your tongue after the first bite? That’s when you’ll reach for the bread again.
- Pasta’s Best Friend: This isn’t just for pasta—it’s the star. Toss it with linguine for a quick weeknight dinner, but also? Slather it on grilled chicken, mix it into scrambled eggs, or drizzle it over roasted veggies. (Yes, even on a Tuesday night.) The basil keeps it fresh, the Parmesan makes it rich, and the pine nuts add crunch no matter what you pair it with.
- Makes Ahead Magic: I double the batch and store it in the fridge for up to five days—no weird aftertaste, just richer flavor. The olive oil and Parmesan actually improve with time, and the pine nuts stay crisp. Freeze half in ice cube trays if you’re feeling fancy; thaw and stir into soups or sauces later. Less stress, more flavor.
Step-by-step instructions for Martha Stewart's pesto sauce recipe
This classic pesto comes together faster than you'd expect—just a few minutes of blending and you'll have vibrant, restaurant-quality sauce.
Toast the Pine Nuts for Maximum Flavor
Heat a dry skillet over medium heat and add the 0.5 cup toasted pine nuts. Toast them for 3-4 minutes, stirring constantly, until they turn a rich golden brown and release their nutty aroma. This toasting step is crucial—it deepens their flavor and prevents them from tasting raw in the final sauce.
Watch carefully as they toast—they burn quickly. When they're fragrant and just beginning to color, remove them immediately and let them cool for 2 minutes before proceeding. The residual heat will continue cooking them slightly in the blender, so don't let them cool completely.
Blend the Garlic and Basil into a Vibrant Paste
In a food processor fitted with the metal blade, add the 3 cloves garlic cloves and pulse until finely chopped. Then add the 2.5 cups fresh basil leaves and pulse again until the basil is finely minced but not completely puréed—you want some texture to maintain the sauce's fresh character.
Here's the thing—don't over-blend at this stage. You're creating a base, not a smooth sauce. The basil should look like coarse confetti rather than a smooth paste. This ensures your pesto has that perfect balance of freshness and creaminess.
Gradually Add Olive Oil to Create the Signature Texture
With the food processor running, very slowly drizzle in the 1 cup extra-virgin olive oil—about 1 tablespoon at a time. This gradual addition prevents the machine from overflowing and allows the oil to emulsify properly with the basil and garlic. The mixture should begin to look like a thick, vibrant green paste.
I like to pause occasionally to scrape down the sides with a rubber spatula. This ensures all the ingredients are evenly incorporated. The sauce should be thick but pourable—if it's too stiff, we'll adjust it in the next step.
Incorporate Cheese and Seasonings for Depth
Add the 0.75 cup freshly grated Parmesan cheese, 0.5 teaspoon diamond crystal kosher salt, and 0.25 teaspoon freshly ground black pepper to the food processor. Pulse until the cheese is fully incorporated and the mixture is completely smooth. Taste and adjust seasoning if needed—you might want to add a pinch more salt or pepper to suit your preference.
Now add the 1 tablespoon lemon juice and pulse once more. The lemon brightens the flavors and balances the richness of the olive oil and cheese. If the pesto is too thick at this point, add 1-2 teaspoons of water at a time until it reaches your desired consistency—it should coat the back of a spoon but still be spreadable.
Adjust Consistency and Store Properly
Transfer the pesto to a bowl and taste it one final time. If it needs thinning, add more olive oil 1 teaspoon at a time until it reaches your preferred texture. For a smoother sauce, blend again briefly. For more texture, leave it slightly chunky.
This pesto keeps beautifully in the refrigerator for up to 5 days, covered with a thin layer of olive oil to prevent browning. For longer storage, freeze it in ice cube trays and transfer to a container—perfect for adding to pasta, soups, or sandwiches whenever you need a quick flavor boost.
Pro Tips For Making Martha Stewart Pesto Sauce
- TOAST NUTS LOW: Use a dry skillet on medium-low heat—pine nuts burn faster than you’d think. Stir constantly and pull them off the moment they’re golden, not brown, or you’ll end up with bitter bits instead of nutty crunch.
- PULSE BASIL GENTLY: Don’t over-blitz the basil in the food processor—just pulse until it’s finely chopped, not pureed. You want texture, not a green paste. If it looks too smooth, you’ve gone too far.
- GRATE PARMESAN FRESH: Skip the pre-grated stuff—it’s full of anti-caking agents that dull the flavor. Use a microplane or fine grater right before mixing, and aim for about ½ cup. The cheese should be room temperature for even distribution.
- SALT THE OIL FIRST: Add a pinch of salt to the olive oil before blending—it balances the basil’s brightness and rounds out the garlic. I learned this the hard way when my pesto tasted one-note. Trust me, it makes a real difference.
Essential equipment for great martha stewart pesto sauce
Food Processor Essentials
Your food processor is the star of this recipe—specifically, a model with a 3-cup capacity like the Ninja BN601 or Cuisinart DFP-14BCNY. The metal blade is non-negotiable for proper emulsification, and a wide-mouth feed tube makes adding olive oil easier.
If you're using a smaller processor, work in batches to avoid overflowing. I've found that the Ninja's 1000-watt motor handles the oil addition smoothly without stalling. 🌿
Cheese Graters for Freshness
Never use pre-grated Parmesan—it contains anti-caking agents that make your pesto grainy. Instead, invest in a microplane or box grater like the OXO Good Grips. For maximum efficiency, I use a KitchenAid Cheese Grater with its fine-hole disk, which gives you the perfect balance of texture.
Grate the cheese directly over the food processor bowl to minimize mess. Freshly grated cheese makes all the difference in texture and flavor. 🧀
Measuring Tools for Precision
For accurate measurements, use a stainless steel measuring cup for olive oil and a small kitchen scale for the Parmesan (about 75 grams for the ¾ cup). A spoon rest like the OXO Good Grips keeps your garlic and basil organized while prepping.
I also recommend a fine-mesh strainer if you prefer a smoother pesto—just press the mixture through after blending. Precision in measurements ensures consistent results every time. 📏
Olive Oil Bottle with Pour Spout
A glass bottle with a pour spout (like California Olive Ranch or Bertolli) makes adding olive oil in 1-tablespoon increments much easier than a traditional decanter. The spout gives you better control, preventing spills while blending.
If you're using a smaller bottle, consider transferring the oil to a measuring cup before adding it to the processor. This small upgrade saves time and reduces mess. 🫒
Storage Containers for Freshness
For short-term storage, use amber glass jars (like Ball Mason Jars) to protect the pesto from light, which can degrade flavors. For long-term freezing, silicone ice cube trays are perfect—they portion the sauce neatly, and you can pop out just what you need.
Label containers with dates to track freshness. I also keep a small airtight container in my fridge for quick access. 🧊
Optional: Mortar and Pestle
If you prefer a traditional approach, a marble mortar and pestle (like KitchenAid's 8-inch) works beautifully for small batches. This method creates a more rustic texture and deeper flavor, but it requires more elbow grease.
I reserve this for special occasions when I want that authentic, handcrafted touch. It's also a great backup if your food processor is occupied. 💪

Frequently asked questions
Can I use walnuts instead of pine nuts in Martha Stewart's pesto?
Walnuts add a richer, earthier flavor that works beautifully. Just toast them first for 3-4 minutes until fragrant, then proceed with the recipe as written. For a smoother texture, blend the walnuts slightly longer than pine nuts, but keep some texture for that authentic pesto feel.
Why does my pesto turn brown after refrigerating?
This happens when basil oxidizes from exposure to air and light. To prevent it, always store pesto in an airtight container covered with a thin layer of olive oil. For extra protection, use amber glass jars or wrap tightly with plastic wrap pressed directly against the surface.
How can I make this pesto nut-free?
Swap the nuts for ¼ cup sun-dried tomatoes or ½ cup roasted red peppers for a vibrant, nut-free version. For extra creaminess, add ¼ cup nutritional yeast or ¼ cup avocado to replace the nutty richness. The texture will be slightly different but still delicious—just blend everything together until smooth.
Can I freeze homemade pesto sauce?
Yes, but freeze it in 1-tablespoon portions using ice cube trays for easy use later. Once frozen, transfer cubes to a freezer bag. Thaw overnight in the fridge, then give it a quick pulse in the food processor to restore texture. The lemon juice helps preserve freshness during freezing.
What's the secret to Martha's perfect pesto texture?
The key is balancing fresh basil with just enough olive oil to create a thick, spreadable sauce—not too chunky, not too smooth. Pulse the basil until it's finely minced but still has visible flecks, then add oil gradually while processing. For extra smoothness, strain through a fine-mesh sieve after blending.
