This recipe started with one goal:
How many vegetables can I sneak into a spaghetti sauce… without anyone noticing?

And somehow, this turned into one of the best spaghetti sauces I’ve ever made.

We’re blending bell peppers, broccoli, kale, onion, and garlic into a smooth base, then cooking it down with seasoned ground beef and marinara. The result? A rich, hearty, classic-tasting meat sauce that just happens to be loaded with vegetables.

It’s perfect for:
