These 4-ingredient slow cooker jumbo shells are the kind of easy supper that saves a busy day. Using raw dry jumbo shells right in the crock pot keeps prep simple, and the slow cooker does the work of softening the pasta while everything cooks together into a cozy, cheesy pasta dinner. It has the comfort of a baked pasta dish without the extra steps, which makes it especially handy for family meals, potlucks, or evenings when you want something filling with almost no fuss.
Serve these jumbo shells with a crisp green salad, garlic bread, or simple steamed green beans for an easy meal. If you are planning a casual National Eat Outside Day dinner, this dish also pairs nicely with fresh fruit, iced tea, and a big spoon so everyone can scoop out warm, saucy shells right onto their plates.
4-Ingredient Slow Cooker Jumbo Shells
Servings: 6
Ingredients
1 (12-ounce) box raw dry jumbo pasta shells
1 (24-ounce) jar pasta sauce
2 cups shredded mozzarella cheese
2 cups water
Directions
1. Spread the raw dry jumbo shells in an even layer in the bottom of a slow cooker.
2. Pour the pasta sauce and water over the shells, making sure the shells are as evenly covered as possible.
3. Cover and cook on low for 3 to 4 hours, checking near the end of cooking time, until the shells are tender.
4. Sprinkle the mozzarella cheese evenly over the top, cover again, and cook for 10 to 15 minutes more until the cheese is melted. Spoon onto plates and serve warm.
Variations & Tips
For extra flavor: If you have room for one more pantry helper outside the 4 main ingredients, a spoonful of Italian seasoning or a little garlic powder adds a nice boost. It is not necessary, but it can make the sauce taste more like it simmered all day.
For picky eaters: Keep the recipe just as written for a very kid-friendly version. If your family likes a smoother texture, use a plain marinara without vegetable chunks so the shells stay simple and familiar.
For best texture: Try to keep the shells in as even a layer as possible so they cook at the same rate. Slow cookers can vary, so start checking around the 3-hour mark. If the pasta looks dry before it turns tender, add a small splash of water.
To make it heartier: You can add cooked ground beef, cooked Italian sausage, or a layer of ricotta if you do not need to keep it at 4 ingredients. Those additions make it feel even more like a classic baked pasta dinner.
For easy serving outdoors: If you are taking this outside for a backyard meal, switch the slow cooker to warm once the cheese melts. That helps the shells stay tender and makes it easy for everyone to serve themselves.
