An easy pasta sauce you can make in minutes, boosted with the flavor and nutrition of roasted vegetables. Read on to learn the simple trick I use to speed up cooking this versatile sauce.
I love quick, practical meals—especially with a small baby at home. If dinner is ready in 30 minutes, I consider it a win. If I can make a large batch of a core component that transforms into several different dishes, then I’ve truly saved time and stress. This roasted vegetable and tomato pasta sauce is one of those make-ahead lifesavers.
What’s in the pasta sauce?
At its core, this sauce is a sheet-pan of roasted vegetables combined with a bottle of tomato passata and a few basic seasonings. The passata is my speed-cooking secret because it’s already smooth and saucy, so it doesn’t need to reduce for a long time. The vegetables add sweetness and depth.
- Red bell pepper
- Zucchini
- Carrot
- Onion
- Garlic
How to roast vegetables
Roasting concentrates the vegetables’ natural sweetness and gives the sauce a lightly caramelized flavor. It also softens everything so the sauce blends smoothly.
Steps:
- Preheat the oven to 425°F (220°C).
- Cut the bell peppers, zucchini and carrots into roughly equal pieces so they cook evenly. Quarter the onion and peel the garlic cloves.
- Toss all the vegetables with olive oil, dried oregano, salt and black pepper.
- Spread the vegetables in a single layer on a baking sheet and roast for about 30 minutes, until tender and lightly browned.
How to make the pasta sauce
Once the vegetables are roasted and slightly cooled, transfer them to a bowl and puree. I prefer using a hand blender so the sauce stays a bit chunky and textured; if you want a completely smooth sauce, use a countertop blender.
Mix in the tomato passata and taste for seasoning. This recipe yields about 5 to 6 cups of sauce—plenty to use right away and to freeze for later.
Storage tip: I normally use about 2 cups and freeze the rest in 1-cup portions using zip-top bags or mason jars. The sauce keeps well in the freezer for 3 to 4 months. If you freeze in jars, leave headroom for expansion; zip-top bags are usually easier to thaw.
What to use the pasta sauce on
This sauce works beautifully anywhere you’d use a tomato-based sauce. Ideas:
- Stir it through any tomato-based pasta to boost vegetables and flavor.
- Add 1 cup to a lasagna meat sauce for extra body and nutrition.
- Use about 1 cup in a keema (minced meat) curry to add moisture and depth.
- Use it as a simple marinara replacement—perfect for meatballs, baked pasta or as a dipping sauce.
I usually don’t simmer this sauce before storing because the passata provides a ready-to-use texture. When using it in a dish, I bring it up to a simmer with any additional ingredients—cream, chili flakes, or reserved pasta water—until the sauce reaches the desired consistency. Roasting gives the sauce a subtle sweetness; add chili flakes, extra salt and pepper to taste depending on how you plan to serve it.

Notes
- I freeze leftover sauce in 1-cup zip-top bags for easy thawing—dip the sealed bag in warm water for a few minutes or defrost in the microwave.
- If you freeze in jars, always leave space at the top for expansion to avoid breakage.
- This sauce is a flexible base: increase herbs, add olives or capers, or fold in cooked protein to make different meals.
