Brown the meat. In a skillet, cook the ground beef (or sausage) with onions and garlic until browned. Drain the grease, unless you want greasy soup vibes.
Dump it in the crockpot. Add the meat mixture, crushed tomatoes, tomato paste, broth, and Italian seasoning. Stir like you’re pretending to know what you’re doing.
Cook low and slow. Set the crockpot to low for 6–7 hours, or high for 3–4 hours. This is your “Netflix and ignore the kitchen” time.
Add noodles later. About 30 minutes before serving, toss in the broken lasagna noodles. Don’t put them in too early unless you want lasagna mush.
Cheese it up. Right before serving, stir in mozzarella. Scoop into bowls, then dollop ricotta and sprinkle Parmesan on top.
Garnish and serve. Add basil or parsley for fancy vibes. Then grab a spoon and dig in.
