Crockpot Creamy Garlic Pasta

This crockpot pasta is the answer when you want something comforting but don’t want to spend hours cooking.

The magic happens in the slow cooker where garlic transforms into something sweet and mellow over a few hours, creating a sauce that tastes like it took effort but actually requires minimal hands-on work.

Cook the pasta separately and stir it in at the end so everything stays tender instead of turning into mush.

Why You’ll Love It

• Minimal prep work, maximum flavor from slow cooking.
• Vegetarian-friendly and naturally satisfying without meat.
• The sauce comes together completely in the crockpot with no stovetop juggling required.
• Garlic flavor is deep and mellow, not sharp or overwhelming.
• Feeds a crowd and reheats well for leftovers.
• Penne pasta stays al dente because you add it at the very end.

Ingredients

For the Sauce

• 8 cloves garlic, minced
• 4 tablespoons butter
• 8 ounces cream cheese, cubed
• 2 cups chicken or vegetable broth
• 1 cup heavy cream
• 1 cup grated Parmesan cheese
• 1 teaspoon Italian seasoning
• Salt and black pepper to taste

For Assembly

• 1 pound penne pasta
• 2 tablespoons fresh parsley, chopped

Steps

1. Add minced garlic and butter to your crockpot and stir to combine.
2. Cut the cream cheese into cubes and add it to the crockpot along with the broth and Italian seasoning.
3. Cover and cook on LOW for 2 to 3 hours, stirring occasionally to help the cream cheese dissolve.
4. After the cooking time, stir the sauce until smooth and creamy.
5. While the sauce is finishing, cook the penne in salted boiling water until al dente according to package directions, then drain well.
6. Stir the heavy cream and Parmesan into the garlic sauce in the crockpot.
7. Add the cooked penne and toss everything together until the pasta is completely coated.
8. Taste and adjust salt and pepper as needed.
9. Garnish with fresh parsley and serve immediately.

Helpful Tips and Substitutions

Cook the penne separately so you have control over texture and prevent the pasta from absorbing too much liquid and becoming mushy.

If you prefer a lighter sauce, use half-and-half instead of heavy cream or reduce the amount of cream cheese slightly.

Fresh garlic is essential here since the slow cooking really brings out the flavor, so skip the jarred version.

You can swap the Parmesan for pecorino romano for a sharper, saltier bite.

For extra vegetables, stir in fresh spinach or mushrooms during the last 30 minutes of cooking, or add sauteed broccoli after cooking.

An immersion blender is helpful if you want a completely smooth sauce, though it’s not required.

Serving Ideas

Serve it straight from the crockpot with a simple green salad and crusty bread to soak up the extra sauce.

Top each bowl with fresh basil or additional Parmesan for more richness.

This pasta works as a main course for weeknight dinners or as a vegetarian centerpiece for entertaining.

Make-Ahead and Storage

You can prep the garlic, butter, and cream cheese the morning of and store them in the crockpot insert in the refrigerator, then add the broth when you’re ready to cook.

Leftovers keep for up to 4 days in an airtight container in the refrigerator.

Reheat gently on the stovetop with a splash of broth or cream to restore the sauce consistency.

You can also freeze the finished pasta for up to 3 months, though the cream sauce may separate slightly when reheated.
