One Pot Creamy Garlic Pasta Recipe Ingredients

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 5 garlic cloves, finely minced
• 4 cups low-sodium chicken broth or vegetable broth
• 1 cup whole milk
• 12 ounces uncooked penne pasta
• 1 teaspoon Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon ground black pepper
• ¼ teaspoon crushed red pepper flakes, optional
• ¾ cup heavy cream
• 1 cup finely grated Parmesan cheese
• 2 tablespoons chopped fresh parsley
• Additional Parmesan and black pepper, for serving

How to Make One Pot Creamy Garlic Pasta

1. Melt the butter.
   Place a large, deep skillet or Dutch oven over medium heat. Add the butter and olive oil, allowing the butter to melt completely.The olive oil helps keep the butter from browning too quickly while adding a little extra richness.
2. Cook the garlic.
   Add the minced garlic and cook for about 30 seconds, stirring constantly.Stop as soon as the garlic smells fragrant. Do not let it turn dark brown, or it may give the finished sauce a bitter taste.
3. Add the cooking liquid.
   Pour in the chicken broth and milk. Stir in the Italian seasoning, salt, black pepper, and crushed red pepper flakes, if using.Increase the heat to medium-high and bring the mixture to a gentle boil.
4. Add the pasta.
   Stir the uncooked penne directly into the simmering liquid. Make sure most of the pasta is covered.Reduce the heat to medium-low. Keep the liquid at a steady simmer rather than a rapid boil, which can cause the milk to scorch.
5. Cook until tender.
   Cook the pasta uncovered for 13 to 16 minutes, stirring every two or three minutes.Stir more frequently toward the end because the sauce thickens as the liquid reduces. Scrape along the bottom of the pan so no pasta sticks.
6. Check the consistency.
   Taste one piece of pasta. It should be tender but still have a slight bite in the center.If the pasta is still firm and most of the liquid has disappeared, add more broth or water, ¼ cup at a time, and continue cooking.
7. Add the cream.
   Reduce the heat to low and pour in the heavy cream. Stir gently until it is fully incorporated.Let the mixture warm for about one minute, but do not allow it to boil rapidly after adding the cream.
8. Stir in the Parmesan.
   Remove the pan from direct heat. Add the Parmesan gradually, stirring after each addition until the cheese has melted into the sauce.The sauce may look slightly loose at first. Let the pasta rest for three to five minutes, and it will thicken as it stands.
9. Finish and serve.
   Stir in the chopped parsley. Taste and add more salt or black pepper if needed.Spoon the pasta into bowls while warm and finish with additional Parmesan, parsley, or crushed red pepper.

Recipe Notes and Tips

Stir the pasta regularly

Because everything cooks in one pan, the pasta can settle and stick to the bottom. Stir every few minutes, especially once the liquid begins to reduce.

A wide skillet also helps the pasta cook more evenly than a narrow saucepan.

Use freshly grated Parmesan

Freshly grated Parmesan melts smoothly into the warm sauce. Packaged pre-shredded cheese may contain anti-caking ingredients that can make the sauce grainy.

Add the cheese after removing the pan from direct heat. Excessive heat may cause it to clump or separate.

Adjust the sauce before serving

The sauce thickens quickly as the pasta cools. If it becomes too thick, stir in a splash of warm broth or milk.

If it seems too thin, let the pasta rest uncovered for several minutes before serving.

Add a protein

Stir in two cups of chopped cooked chicken during the final few minutes. Cooked shrimp, turkey sausage, or leftover roasted turkey can also be added.

Make sure any added meat is already fully cooked before mixing it into the pasta.

Add vegetables

Fresh spinach can be stirred in with the cream and cooked until wilted. Sautéed mushrooms, peas, broccoli, or sun-dried tomatoes also pair well with the garlic-Parmesan sauce.

Make-ahead and storage

This pasta is creamiest immediately after cooking, but leftovers can be refrigerated in an airtight container for up to three days.

Reheat gently over low heat with a splash of milk or broth. Stir frequently until the sauce loosens and the pasta is hot throughout.

Freezing is not recommended because cream-based sauces may separate after thawing.

Frequently Asked Questions

Can I make one-pot creamy garlic pasta without heavy cream?

Yes. Replace the heavy cream with an equal amount of half-and-half or whole milk. The sauce will be slightly lighter and may take another minute or two to thicken.

For the richest result without cream, add two tablespoons of cream cheese with the Parmesan.

Why is my garlic pasta sauce grainy?

The Parmesan may have been added while the pan was too hot, or pre-shredded cheese may not have melted evenly. Remove the pasta from direct heat and add finely grated Parmesan gradually while stirring.

Can I use a different pasta shape?

Yes. Rotini, rigatoni, farfalle, shells, or elbow macaroni can replace the penne. Cooking time and liquid needs may vary, so check the pasta frequently near the end.

What should I serve with creamy garlic pasta?

Serve it with roasted chicken, baked fish, garlic bread, or a crisp green salad. Roasted broccoli, green beans, and asparagus also balance the rich Parmesan sauce.

A Simple Bowl of Comfort

There is something especially satisfying about watching broth, garlic, and pasta turn into a creamy dinner without ever reaching for a second pot. Serve it while the sauce is glossy and warm, with extra Parmesan scattered over the top and plenty of black pepper in every bowl.
