How to Make One-Pot Creamy Tomato Pasta | Easy 20-Minute Dinner

1. Heat the olive oil in a large deep skillet or wide pot over medium heat. Add the chopped onion and sauté until soft and translucent, about 3-4 minutes.
2. Add the minced garlic and cook for 30 seconds until fragrant, stirring constantly to avoid burning.
3. Pour in the crushed tomatoes, vegetable broth, and dried Italian seasoning. Stir well to combine, then bring the mixture to a gentle boil.
4. Add the dried penne pasta to the pot, making sure it’s submerged in the liquid. Reduce the heat to medium-low, cover, and simmer for about 12-15 minutes, stirring occasionally, until the pasta is tender and most of the liquid is absorbed.
5. Once the pasta is cooked, stir in the half-and-half and grated Parmesan cheese until the sauce is creamy and smooth. Season with salt, pepper, and red pepper flakes if using. Let it cook for another 2 minutes to thicken.
6. Remove from heat and let the pasta rest covered for 2 minutes. This helps the sauce thicken and flavors to meld.
7. Scoop the creamy tomato pasta into bowls, garnish with fresh basil leaves and more Parmesan cheese, and serve immediately.

Tips for the Best Results

• Use a wide, deep skillet or pot to allow enough liquid for the pasta to cook evenly.
• Stir occasionally while cooking the pasta to prevent sticking but not too often to keep the sauce creamy.
• For a richer sauce, swap half-and-half with heavy cream or add a tablespoon of cream cheese.
• Adjust the seasoning at the end—tomato sauces can vary in acidity and saltiness.
• Add sautéed mushrooms, spinach, or cooked chicken for extra nutrition and flavor.

Storage and Reheating

Store any leftover creamy tomato pasta in an airtight container in the refrigerator for up to 3 days. The sauce may thicken as it cools, so add a splash of milk or broth when reheating to bring back the creamy texture.

You can also freeze the pasta for up to 2 months. Thaw overnight in the fridge and reheat gently on the stovetop or microwave, stirring occasionally to ensure even warming.

Frequently Asked Questions

Can I use a different type of pasta?

Yes! While penne works great in this recipe, you can use fusilli, rotini, or other short pasta shapes that cook well in liquid. Just adjust the cooking time if needed.

Is there a dairy-free version of this recipe?

Absolutely. Replace the half-and-half with a plant-based milk like coconut or oat milk, and use a dairy-free Parmesan alternative or nutritional yeast to keep it creamy and flavorful.

How spicy is this pasta?

The red pepper flakes add a mild heat, but they’re optional. You can leave them out for a milder dish or add more if you like it spicy.

Can I prepare this recipe ahead of time?

You can prep the garlic and onion ahead, but it’s best to cook the pasta fresh to maintain its texture. Leftovers are delicious but will be softer after reheating.
