Vegetable Italian Spaghetti Sauce

This is the spaghetti sauce for when the summer garden is overflowing. It packs three colors of bell pepper, zucchini, and yellow squash into a herb-rich tomato base, no meat required.

Finely chopping the vegetables is the key move. Cut small, they melt into the sauce over the long simmer, adding sweetness and body without leaving big chunks, so it still coats pasta like a proper marinara.

That slow cook is where the magic happens. Four to six hours of gentle simmering lets the vegetables break down, the herbs infuse, and the tomatoes reduce into a thick, deeply savory sauce. There’s no shortcut for that kind of depth.

A generous hand with oregano, rosemary, thyme, basil, and parsley gives it real Italian character. It makes a big batch and freezes beautifully, so cook once and stock the freezer for easy weeknight dinners.

Chef Tips

• Chop the vegetables fine so they melt into the sauce instead of staying chunky.
• Simmer low and slow, stirring now and then, until it reaches the thickness you want.
• A pinch of sugar, which the recipe includes, balances the acidity of the canned tomatoes.
• Pull the bay leaves before serving, and cool the sauce fully before freezing in portions.

Variations

• Stir in mushrooms, eggplant, carrots, or any other summer veg you have on hand.
• Add a splash of red wine or a Parmesan rind while it simmers for more depth.
• Brown Italian sausage or ground beef into it for a meaty version.
