Ingredients
This is what you'll need to make this sauce. See the recipe card for quantities.
- Cream: This is optional to make this a creamy tomato sauce. Use coconut milk, cashew cream, or a thick plant-based milk like oat milk for best results.
- Veggies Broth: I love using Better Than Bouillon paste in my recipes because it adds a rich, concentrated flavor that’s easy to customize for a rich flavor.
- Sugar: The sugar is optional but does cut back the acidity of the tomatoes. Adjust to your liking.
Variations
- Experiment with Vegetables: This sauce is versatile and works well with other veggies like cauliflower. Stick to soft, mild veggies for the best results.
- Roasted Flavor: Roast the veggies instead for a deeper, roasted flavor.
- Add Lentils: Like in my Best Vegan Lasagna, red lentils disappear in a sauce like this. Add about ¼ cup when you add the veggie broth. It thickens up the sauce, so you will need to add a bit more broth to the sauce - about ¾ cup will do the trick.
- Chunky Style: Blend the sauce lightly for a chunkier texture. You can also use a food processor to shred or chop the veggies so finely they are hardly detectable in the sauce and you can skip the blending. This is perfect for rustic pasta dishes.
- Extra Protein: Simmer some tofu crumbles, TVP, or other plant-based meat crumbles after pureeing the sauce for a 'meat sauce.'
How To Make Hidden Veggies Pasta Sauce
For those who like a preview, this is what you'll be doing in the pics below. See the recipe card for complete details.
Step 1: Sauté the Base: Heat olive oil in a large skillet over medium heat. Add chopped onion and garlic, cooking until fragrant and translucent, about 5 minutes.
Step 2: Cook the Vegetables: Stir in zucchini, eggplant, carrot, spinach, and red bell pepper. Cook for about 10 minutes, stirring occasionally, until the vegetables soften slightly and the spinach wilts.
Step 3: Add Tomato Paste and Seasoning: Mix in the tomato paste and Italian seasoning, cooking for 2 minutes.
Step 4: Add Liquid: Then, add chopped tomatoes, vegetable broth, salt, pepper, sugar, and a bay leaf. Reduce the heat to low and let the sauce simmer uncovered, allowing the flavors to meld and the vegetables to soften.
Step 5: Blend the Sauce: Use an immersion blender or transfer to a regular blender in batches to puree the sauce until smooth. Return it to the pot.
Step 6: Optional - Add the cream and mix well. Heat for a minute or two if the cream has cooled down.
Top Tips
- Cut the vegetables into uniform sizes, making the carrots slightly smaller to ensure even cooking.
- There’s no need to fully soften the veggies while sautéing, but you’ll want to cook them long enough to release their flavors and begin to tenderize as they’ll finish cooking in the liquid.
- I’ve had my fair share of blender mishaps, so here’s a tip: never fill the blender more than ½ to ¾, especially with hot liquids. For added safety, cover the lid with a kitchen towel and hold it down firmly with your hand to prevent spills or splatters.
Serving Suggestions
- Toss with your favorite pasta for a quick, wholesome meal.
- Use as a flavorful base for Best Vegan Lasagna With Tofu Ricotta or baked ziti.
- Spread on your 100% Biga Neapolitan Pizza Dough for a veggie-packed pizza night.
- Serve as a dipping sauce for garlic bread or veggie sticks.
- Use as a sauce for stuffed peppers or eggplant for a creative twist.
Storage
- Refrigerator: Store the sauce in an airtight container and keep it in the fridge for up to 5 days.
- Freezer: Freeze in portioned containers or freezer-safe bags, leaving room for expansion, and store for up to 3 months. Thaw in the fridge overnight before reheating.
- Reheating: Warm the sauce on the stovetop over low heat or in the microwave at 50%, stirring occasionally. Add a splash of water or broth if it thickens too much.
Recipe FAQS
Yes. This sauce is incredibly versatile and perfect for experimenting with different vegetables. Cauliflower and yellow squash are great choices, each adding its own unique flavor and nutrients. However, I avoid starchy vegetables like potatoes or sweet potatoes, as they can make the sauce too thick, and watery options like cucumber may dilute the flavor. Similarly, I skip pungent or too-fibrous vegetables like asparagus, as they can overpower the sauce’s mild and balanced flavor. If you focus on soft, neutral veggies like pumpkin or butternut squash that blend well, they won't overwhelm it.
Fresh tomatoes work well in this recipe. Blanching and peeling is recommended for a smoother sauce but it is optional. If you choose to use them, about five to 10-12 Roma or plum tomatoes should do the trick.
Make some fresh pasta in the morning and then layer it in a thermos with vegan meatballs for a cozy lunch option. You can also use it as a pizza sauce on mini pita or tortilla pizzas that are easy to pack and eat cold or warm. Tip: To keep the pasta warm, use a high-quality thermos, fill it with boiling water, close the lid, and let it sit for 5-10 minutes while you prepare your pasta.

- 1 bay leaf
- ¼ cup coconut milk, unsweetened plant-based milk, or cashew cream (optional for creaminess)
Instructions
- Sauté the Base: Heat olive oil in a large skillet over medium heat. Add the chopped onion and garlic, cooking until fragrant and translucent, about 5 minutes.
- Add the Veggies: Stir in the zucchini, eggplant, carrot, spinach, and red bell pepper. Cook for 10 minutes, stirring occasionally, until the vegetables are soft and the spinach is wilted. The vegetables don't have to be completely softened as they will continue to cook in the liquid.

- Simmer: Reduce the heat to low and let the sauce simmer uncovered for 30 - 50 minutes, allowing the flavors to meld and the vegetables to soften further. The longer it cooks, the more flavor it develops.
- Blend Hidden Veggies: Using an immersion blender or transferring to a regular blender in batches, blend the sauce until smooth. Return the sauce to the pot.
- Finish with Creaminess (Optional): Stir in coconut milk, plant-based milk, or cashew cream for a richer, creamier sauce. Taste and adjust seasoning if needed.
- Serve: Toss the sauce with your favorite pasta or use in any recipe calling for a red sauce. Sprinkle with fresh basil or vegan parmesan if desired.
Equipment
Notes
Instead of sauteeing the veggies, roast them in a 425°F oven for about 50-60 minutes. Make sure to keep the garlic skins on when roasting.
Using a standing blender instead of an immersion blender delivers a smoother sauce.
I use chopped Pomi tomatoes that come in a 26-ounce carton.
Cut vegetables evenly, with carrots slightly smaller for even cooking.
Don’t fill the blender to avoid a blender disaster. Cover the lid with a towel and hold the top firmly to avoid spills.
