What is one pot pasta?
One-Pot Pasta is a dish where all of the ingredients are cooked in the same pot and at the same time, resulting in a flavorful and quick meal that requires very little effort and clean up. I would like to mention that this is not an “authentic Italian” recipe. I don’t believe Italians cook pasta this way. But it is a very EASY, QUICK, and DELICIOUS way to cook pasta.
Main Ingredients
- Pasta. I think spaghetti works the best here. Other types of pasta can also be used.
- Tomatoes. I suggest using cherry or grape tomatoes because they have more flavors and tend to be sweeter.
- Spinach. Spinach adds a nice touch of color, flavor, and extra nutrients.
- Onions. Onion adds a great flavor to the broth. It will soften and won't be noticeable in the pasta.
- Garlic. You can add more or less garlic depending on personal preference.
- Parsley. Fresh parsley is the way to go. Dried ones will not taste as great.
- Olive Oil.
- Parmesan. Optional, but recommended.
- Seasonings. Salt, pepper, and red pepper flakes to add a bit of heat.
How to Make One Pot Pasta with Spinach
1. In a large pot or a Dutch oven, combine all of the ingredients (excluding the Parmesan) and add 4 cups of water.
2. Bring to a boil. Reduce the heat to medium-low and simmer, uncovered, until the pasta is cooked through and the liquid has reduced, about 8-10 minutes. Stir in the Parmesan.
3. Serve immediately. Garnish with more Parmesan and a drizzle of olive oil.
Helpful Tips and Tricks
Stir the pasta while cooking. Stir the pasta every few minutes to make sure it doesn’t get stuck together, since there is no extra water used in this recipe.
Adjust the seasonings to your taste. Skip the red pepper flakes, if you are not a fan. Add a bit of your favorite seasoning, if you wish.
Add more water, if necessary. There are some types of pasta that tend to cook longer and may require some extra water to fully cook. If you feel that the pasta needs more cooking, just keep adding more water until it cooks through.
Add proteins. You can also add some chicken, sausage, or kielbasa pieces with the rest of the ingredients.

Recipe Variations

- Sausage
- Kielbasa
- Bell Peppers
- Fresh Basil
You can also mix in about 2 tablespoons of pesto sauce at the end of cooking.
What's the Best Pot for One Pot Pasta?
I absolutely love using cast iron pots. I think a 3.6-quart cast iron casserole pan is the best for this recipe. It is just the perfect size for one pot dishes, and also for risottos, paellas, and more! That said, you can use any pot that fits all of the ingredients together.
Would Gluten-Free Pasta Work in this Recipe?
Yes. You can use gluten-free pasta in this recipe. However, you might need to use about ½ cup more water. Also, if you let gluten-free pasta sit for too long before you serve it, it will absorb all of the remaining liquid and get a bit mushy. I suggest serving gluten-free pasta right away.
How to Store and Reheat
Store this pasta in the fridge, covered with a lid for up to 3 days. When ready to enjoy, add a splash of water and reheat on the stove, just until heated through.

Delicious! I added some fresh basil from my garden and some cooked chicken I had on hand. It was very good and I will definitely be making it again!

Yay! Thanks for the rating, Donna!
Shae says
Soooo good! Only substitutions (due to ingredients on hand) was whole grain penne pasta instead of spaghetti and shredded mozzarella instead of Parmesan. Still turned out perfect!!!
Tania Sheff says
That's great to hear! Thank you for reporting back, Shae!
Joni says
Made as directed except used penne noodles from ZenB (yellow pea noodles). It turned out awesome! It looked a little saucier than yours but that was great actually. I thought afterwards to add shrimp in would be good. Next time!

Thanks for the feedback, Joni! Happy Easter!

I followed this to a T except for omitting the red pepper since my kids were going to be eating it. I've always been weary of one pot recipes but this was really flavorful and easy. The parmesean got a little clumpy so next time I might just leave it out or only sprinkle a little on top once its plated. Over all this was great and I'll make it again for sure. Don't pour out the liquid at the end its very flavorful and it all works out once you plate it.
