There’s something about a pot of sauce simmering on the stove that makes the whole kitchen feel cozy. Traditionally, Sunday sauce is loaded with meat and takes hours to cook, but I wanted to make a version that gives you that same rich, hearty, slow cooked flavor without the meat or the all day cooking time.
This vegetarian Sunday sauce is packed with onions, carrots, zucchini, garlic, Italian herbs, and a little Calabrian chili paste for a kick. The vegetables cook down into the sauce, making it thick, flavorful, and surprisingly hearty.
And the best part? It tastes like it simmered all day, but you can have it ready in about an hour.
Serve it over your favorite pasta with plenty of parmesan and fresh basil, or make a big batch and save it for an easy dinner during the week. This is one of those recipes that honestly gets even better the next day.
Why You’ll Love This Vegetarian Sunday Sauce
It’s packed with vegetables. Onions, carrots, zucchini, and plenty of garlic give this sauce so much flavor without needing meat.
The Calabrian chili paste makes it. You only need a spoonful, but it adds a subtle spicy, slightly smoky heat that takes the sauce to another level.
It tastes slow cooked. Letting the vegetables cook down with the tomatoes gives you that rich Sunday sauce flavor without needing to babysit a pot for hours.
It’s perfect for meal prep. Make a big batch on Sunday and you have an easy pasta dinner ready to go throughout the week.
What to Serve With Vegetarian Sunday Sauce
This sauce is obviously made for pasta, but you can use it in so many different ways.
Try it with:
Spaghetti
Rigatoni
Penne
Bucatini
Gnocchi
Lasagna
Stuffed shells
Baked pasta
Crusty garlic bread
You can also use the sauce as a base for a vegetable lasagna or baked pasta when you want something extra cozy.
Tips for the Best Vegetarian Sunday Sauce
Finely dice the vegetables. Since the vegetables cook directly into the sauce, cutting them into small pieces helps them soften and blend into the tomatoes.
Don’t skip the Calabrian chili paste. If you like a little heat, this is what gives the sauce its signature flavor. Start with less if you’re sensitive to spice.
Let it simmer. Even though this is a quicker version of Sunday sauce, giving it time to simmer is what brings all the flavors together.
Make extra. This sauce is perfect for meal prep and freezes really well. Let it cool completely before storing it in an airtight container.
Can I Make This Sauce Ahead of Time?
Absolutely. In fact, I think it tastes even better the next day. Store the cooled sauce in the refrigerator and reheat it on the stove when you’re ready to use it.
You can also freeze the sauce for an easy dinner later. Just thaw it in the refrigerator and warm it gently on the stove.
How Spicy Is This Sauce?
The Calabrian chili paste gives the sauce a nice kick, but it shouldn’t overpower everything else. If you want a milder sauce, start with less chili paste and add more at the end if needed.
If you love spicy food, go ahead and add a little extra. I fully support that decision.
The Sunday Sauce Shortcut
This is the kind of recipe I love having in my back pocket. You get all the cozy, rich, slow cooked flavor of Sunday sauce, but you don’t need a giant pot of meat or an entire afternoon to make it.
Make a big pot, boil some pasta, grab the parmesan, and call it dinner.
Heat the olive oil in a large pot or Dutch oven over medium heat. Add the smashed garlic cloves and let them cook for a minute or two to flavor the oil.
Add the diced onion, zucchini, and carrots. Cook until the vegetables start to soften and the onions become translucent.
Add the Calabrian chili paste along with the salt, sugar, garlic powder, onion powder, paprika, and Italian seasoning. Stir everything together and let it cook for another minute or two. Add the grated garlic and stir everything together.
Pour in the whole peeled tomatoes and use the back of your spoon to gently break them apart.
Let the sauce simmer for about 20 minutes, stirring occasionally. The vegetables will continue to break down into the tomatoes and the sauce will become rich, thick, and full of flavor.
Toss the sauce with your favorite pasta and finish it with parmesan, fresh basil, and an extra drizzle of olive oil. And if you’re anything like me, a little extra Calabrian chili on top never hurts.
