Why You’ll Love this Slow-Simmered Vegetable Bolognese
While traditional Bolognese relies on meat as its star ingredient, this vegetable-packed version delivers all the comforting richness you crave with an extra nutritional punch.
I’m talking about hidden shredded zucchini and carrots that melt into the sauce, creating that hearty texture you love.
The slow simmering is where magic happens. Those two hours of gentle cooking allow the wine to reduce, the tomatoes to sweeten, and all those Italian herbs to infuse every spoonful.
Can you imagine the aroma that’ll fill your kitchen? Trust me, your family won’t miss the meat—they’ll be too busy asking for seconds.
What Ingredients are in Slow-Simmered Vegetable Bolognese?
Our vegetable Bolognese combines the rich, savory flavors of traditional Italian sauce with nutritious vegetables that practically melt into the mixture.
What I love about this recipe is how versatile it is—you can adjust the heat level by adding more or fewer red pepper flakes, or swap in seasonal vegetables depending on what looks fresh at the market.
The combination of crushed tomatoes and tomato sauce creates the perfect texture, while the red wine adds depth that develops beautifully during the slow simmer.
- 2 (28 ounce) cans crushed tomatoes

- 3 cups shredded zucchini
- 1 1/2 cups shredded carrots

When shopping for ingredients, quality really matters for a sauce that simmers this long.
Look for San Marzano tomatoes if your budget allows—they have less acidity and a sweeter flavor profile.
For the wine, don’t feel pressured to use anything fancy, but do choose something you’d actually drink.
The alcohol cooks off, leaving behind complex flavors that make all the difference.
And if you’re grating your own vegetables (which I recommend for the freshest taste), use the large holes of a box grater for perfect texture that won’t turn mushy during cooking.
How to Make this Slow-Simmered Vegetable Bolognese
Making this incredible vegetable Bolognese is all about patience—the slow simmer is what transforms simple ingredients into something magical.
Start by heating 1 tablespoon of olive oil in a large, heavy-bottomed pot over medium heat. Add your finely chopped 1/2 onion and cook until translucent, about 3-4 minutes, then add 1 clove of minced garlic and cook for another 30 seconds until fragrant.
Don’t we all love that moment when garlic hits hot oil and the kitchen starts smelling like heaven?
Next, add 1 pound of Italian sausage to the pot, breaking it up with a wooden spoon as it browns. Once the meat is cooked through, stir in 3 cups of shredded zucchini and 1 1/2 cups of shredded carrots.
These vegetables will practically melt into the sauce, adding nutrition and texture without announcing their presence too boldly—perfect for picky eaters who might otherwise turn up their noses at vegetables.
Add 1/2 teaspoon of crushed red pepper flakes (or adjust to your heat preference), 1 tablespoon of dried basil, and 1 teaspoon of dried oregano. Pour in 1 cup of red wine, letting it simmer for a few minutes to burn off the alcohol while concentrating those complex flavors.
Finally, add 2 cans (28 ounces each) of crushed tomatoes and 1 can (20 ounces) of tomato sauce, stirring everything together. Reduce the heat to low, and now comes the most important part—let it simmer, partially covered, for 2 full hours, stirring occasionally.
For the most authentic results and better flavor development, consider using a wok cooking system which provides excellent heat distribution and control during the long simmering process.
For perfect results, use a premium meat thermometer to ensure your sauce maintains a gentle simmer between 180-190°F throughout the cooking process.
This long, slow cooking process allows all the flavors to meld together beautifully. The sauce should thicken slightly and develop a rich, complex taste that’s miles beyond what you’d get from a quick-cooked version.
Serve your gorgeous sauce over pasta of your choice and finish with a generous sprinkle of freshly grated Parmesan cheese. The cheese will melt slightly into the hot sauce, creating little pockets of creamy saltiness that contrast perfectly with the savory Bolognese.
Slow-Simmered Vegetable Bolognese Substitutions and Variations
Despite the name suggesting otherwise, this vegetable Bolognese recipe can be adapted in countless ways to suit your preferences or pantry inventory. I’m all about flexibility in the kitchen, and this sauce welcomes substitutions with open arms.
Don’t have zucchini? Try mushrooms, bell peppers, or eggplant for that meaty texture. The Italian sausage can be swapped for ground beef, turkey, or a plant-based alternative if you’re going fully vegetarian. Not a red wine drinker? Use beef broth instead.
The herbs are negotiable too—fresh herbs work beautifully if you’ve got them. Just remember, whatever your variation, the slow simmer is non-negotiable.
What to Serve with Slow-Simmered Vegetable Bolognese
While we’ve explored the versatility of this hearty sauce, let’s talk about what to pair with your simmering pot of goodness.
The classic choice is pasta—I love a wide pappardelle or sturdy rigatoni that catches all those vegetable bits. But why stop there?
Try spooning this rich sauce over creamy polenta, stuffed into roasted bell peppers, or atop a crusty piece of garlic bread.
A simple green salad with a bright vinaigrette makes the perfect side, cutting through the richness.
Can you imagine a better Sunday dinner? Nothing beats dipping warm, crusty bread into that slow-simmered sauce.
