Ingredients

· 1 bag (about 2 pounds) frozen meatballs, fully cooked

· 1 jar (24 ounces) marinara or pasta sauce

· 12 ounces penne pasta, uncooked

· Optional: 1 teaspoon garlic powder, 1 teaspoon dried Italian herbs, 1/2 teaspoon red pepper flakes, grated Parmesan cheese, or chopped fresh basil for garnish

The three main ingredients are frozen meatballs, marinara sauce, and penne pasta.

How to Make Slow Cooker 3-Ingredient Meatball Penne

1. Prepare the Slow Cooker

Lightly grease the inside of your slow cooker with cooking spray or a small amount of olive oil.

2. Add the Meatballs and Sauce

Pour the marinara sauce into the slow cooker. Add the frozen meatballs and stir gently to coat them evenly. If using garlic powder, Italian herbs, or red pepper flakes, stir them into the sauce now.

3. Cook the Meatballs

Cover and cook on low for 4 to 5 hours or on high for 2 to 3 hours, until the meatballs are heated through and the sauce is bubbling.

4. Cook the Penne

About 30 minutes before the meatballs are done, bring a large pot of salted water to a boil. Cook the penne for 2 minutes less than the package directions so it stays firm. Drain well and set aside.

5. Combine the Pasta and Meatballs

Add the cooked penne to the slow cooker and stir gently to coat it evenly with the sauce and meatballs. If the mixture seems thick, add a splash of pasta water or a little extra marinara.

6. Finish and Rest

Cover and cook on low for another 10 to 15 minutes, until the pasta is tender and fully heated through. Let the dish rest for 5 minutes before serving.

7. Serve Warm

Scoop into bowls and top with grated Parmesan and fresh basil if desired.

Tips for the Best Meatball Penne

Use fully cooked frozen meatballs for the easiest preparation, or homemade meatballs if you prefer.

Do not overcook the penne, as it will continue to soften slightly in the hot sauce.

Stir gently when combining the pasta and meatballs so the meatballs do not break apart.

For a thicker sauce, remove the lid during the last 15 minutes of cooking and let it reduce.

Add a splash of pasta water when mixing to help the sauce cling to the penne.

Taste before adding salt, since the marinara and meatballs already contain seasoning.

Easy Variations

Use ground turkey meatballs, chicken meatballs, or plant-based meatballs for a lighter version.

Swap the penne for rigatoni, ziti, or rotini if you prefer a different pasta shape.

Add a can of diced tomatoes or a spoonful of tomato paste for a richer, more robust sauce.

Stir in a handful of fresh spinach or sliced mushrooms during the last 15 minutes of cooking.

For a spicier kick, use spicy marinara or add extra red pepper flakes.

What to Serve With Meatball Penne

Serve this dish with garlic bread or crusty Italian bread for soaking up the sauce.

A crisp Caesar salad or a simple garden salad with vinaigrette makes an excellent side.

Steamed broccoli, roasted green beans, or sauteed zucchini pair beautifully with the rich sauce.

For a lighter meal, serve it over zucchini noodles or spaghetti squash instead of penne.

How to Store Leftovers

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Reheat gently in the microwave or on the stovetop with a splash of marinara or water to loosen the sauce.

The pasta will absorb liquid as it sits, so add a little sauce or broth when reheating.

This dish can be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use fresh meatballs instead of frozen?

Yes. Fresh meatballs work well, but reduce the cooking time slightly since they do not need to thaw.

Can I cook the pasta directly in the slow cooker?

It is not recommended, as the pasta can become mushy and absorb too much liquid. Cooking it separately gives the best texture.

Can I make this recipe ahead of time?

Yes. Cook the meatballs and sauce in advance, then store covered in the refrigerator. Boil the pasta fresh when ready to serve.

Why is my sauce too thin?

The frozen meatballs may have released extra liquid as they thawed. Remove the lid during the last 15 minutes of cooking to let the sauce thicken.
