The Complete Recipe: 4-Ingredient Slow Cooker Baked Ziti-Style Penne
Prep Time: 5 minutes | Cook Time: 2½–3 hours on LOW | Total Time: 2½–3 hours | Servings: 6-8
Ingredients
-
12 oz penne pasta (uncooked)
-
24 oz marinara sauce
-
2 cups shredded mozzarella cheese
-
1 cup ricotta cheese
Step-by-Step Instructions
Step 1: Layer the Sauce
Spread a thin layer of marinara sauce on the bottom of your slow cooker. This prevents the pasta from sticking.
Step 2: Add Pasta and Cheese
Add the uncooked penne, remaining marinara sauce, ricotta cheese, and half of the mozzarella cheese. Stir gently to combine, making sure the pasta is mostly coated in sauce.
Step 3: Cook
Cover and cook on LOW for 2½ to 3 hours, stirring once halfway through to prevent sticking and ensure even cooking.
Step 4: Top with Cheese
During the last 20 minutes of cooking, sprinkle the remaining mozzarella cheese over the top. Cover and let it melt until bubbly and golden.
Step 5: Serve
Once the pasta is tender and the cheese is melted, serve hot. Spoon directly from the slow cooker.
Pro Tips for the Best Slow Cooker Pasta
-
Prevent Sticking: Stir the pasta gently halfway through cooking to avoid sticking, and make sure the pasta is fully coated in sauce from the beginning.
-
Adjust Sauce: If the pasta absorbs too much liquid, add ¼ to ½ cup of water or broth to keep it creamy.
-
Don’t Overcook: Check for doneness at the 2½-hour mark. Pasta can quickly go from perfectly tender to mushy.
-
Layer Carefully: The thin layer of sauce on the bottom is essential for preventing sticking.
-
Fresh Herbs: A sprinkle of fresh basil or parsley just before serving adds brightness and color.
Optional Add-Ins
-
Cooked ground beef or Italian sausage

Garlic powder or Italian seasoning

Fresh basil or parsley

Red pepper flakes for heat
