One Pot Creamy Spinach Tomato Tortellini
A one-pot pasta that tastes like it simmered all day but is ready in 25 minutes. Creamy, silky, and deeply satisfying — the kind of dinner that makes you look down at the bowl and wonder if you accidentally did something more complicated.
Equipment
- Large Dutch Oven or Heavy Bottom Pot
- Wooden Spoon
- Box grater or microplane
Ingredients
- 1 tbsp olive oil
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 14.5 oz can diced tomatoes, undrained
- 2 cups vegetable or chicken broth
- 1 cup heavy cream
- 1 9 oz package refrigerated tortellini
- 3 cups fresh baby spinach
- 1/2 cup freshly grated Parmesan
- to taste salt
- to taste black pepper
- 1 pinch red pepper flakes
Instructions
- Sauté the aromatics: Heat the olive oil in your pot over medium heat. Add the onion and cook until translucent, about 4 minutes. Add the garlic and cook for 30 seconds until fragrant. (📸 Photo tip: The onions should be soft and slightly golden on the edges, not brown. If they brown, your heat is too high.)
- Build the sauce base: Pour in the undrained diced tomatoes and the broth. Bring to a simmer. Let it bubble for 2-3 minutes so the flavors start to meld.
- Add the cream and pasta: Stir in the heavy cream. Add the refrigerated tortellini in an even layer. Press them down gently so they are mostly submerged in the liquid.
- Cook the pasta: Simmer for 4-5 minutes, stirring gently every minute to prevent sticking. The tortellini will puff up and the sauce will thicken as the pasta releases its starch. Do not walk away — tortellini goes from perfectly tender to mushy fast.
- Wilt the spinach: Turn off the heat. Add the fresh spinach in handfuls, stirring until it wilts completely. This takes about 60 seconds. (📸 Photo tip: The spinach should be bright green and just barely collapsed. Overcooked spinach turns muddy and loses that visual pop.)
- Finish and serve: Stir in the Parmesan until it melts into the sauce. Taste and season with salt, pepper, and a pinch of red pepper flakes. Let it sit for 2 minutes off the heat — the sauce will continue to thicken and get glossier as it rests.
Notes
Do not drain the tomatoes — the juices are part of the liquid ratio. Resist the urge to over-stir; tortellini is delicate. Add the Parmesan off the heat to prevent graininess. Reserve a cup of broth before starting to adjust sauce thickness later. For making ahead, undercook the pasta by a minute and store in the fridge for up to 3 days. Reheat gently on the stovetop with a splash of broth. Freezing not recommended due to dairy separation.
