Can I use canned tomatoes instead of fresh?
Yes. Use one 28-oz can of crushed tomatoes and reduce the simmering time to 10-12 minutes since they cook faster than fresh tomatoes.
What type of cheese works best?
Mozzarella melts smoothly and is traditional, but cheddar, provolone, or a blend also work well. Add it at the end off heat so it doesn't separate.
Can I make this ahead?
Cook through the beef and tomato stage, then refrigerate up to 2 days. Reheat gently, add fresh pasta and cheese when ready to serve.
How do I prevent the pasta from sticking?
Stir occasionally during cooking, especially in the first 5 minutes. If sauce thickens too much, add pasta water or broth to reach desired consistency.
Can I double this recipe?
Yes, but use a larger skillet or Dutch oven and increase cooking time by 5-10 minutes to ensure the beef browns properly and sauce simmers evenly.
