How to Make Slow Cooker Baked Mostaccioli
Step 1: Cook the Meat
In a skillet over medium heat, cook the ground beef or Italian sausage until browned. Add the chopped onion and garlic, cooking until fragrant. Drain excess grease.
Step 2: Prepare the Sauce
Stir the marinara sauce, crushed tomatoes, Italian seasoning, salt, and pepper into the cooked meat mixture. Let it simmer for a few minutes so the flavors combine.
Step 3: Cook the Pasta
Boil the mostaccioli pasta in salted water until just slightly undercooked (about 2 minutes less than the package directions). Drain well.
Step 4: Layer in the Slow Cooker
Lightly grease the slow cooker, then layer the ingredients:
-
A layer of sauce
-
A layer of pasta
-
A sprinkle of mozzarella cheese
Repeat the layers until all ingredients are used, finishing with mozzarella and Parmesan cheese on top.
Step 5: Slow Cook
Cover and cook on low for 2–3 hours or until the cheese is melted and the pasta is fully tender.
Step 6: Serve
Let the dish rest for about 10 minutes before serving. Garnish with fresh basil or parsley if desired.
