This one-pot lasagna soup has all the flavor of classic lasagna — rich tomato broth, tender noodles, ground beef, and gooey cheese — made in under 45 minutes with easy cleanup.
1 tbsp olive oil
1 yellow onion, diced
3–4 garlic cloves, minced

1/4 cup grated Parmesan
1/2 cup ricotta cheese (for topping)
Fresh basil or parsley, for garnish
