When you want a cozy, Italian restaurant-quality pasta dinner in a flash, 15-Minute Creamy Pesto Gnocchi is hard to beat. Soft, pillowy potato gnocchi are boiled until tender, then tossed in a velvety, emerald-green sauce made from basil pesto, heavy cream, garlic, and freshly grated Parmesan cheese.
The secret to a luscious gnocchi sauce that coats every bite without turning heavy or separated is Reserving Starchy Cooking Water and Emulsifying Off Heat. Gnocchi cook rapidly and release concentrated starches into the water. Whisking a splash of that hot, starchy cooking liquid into the cream and pesto creates a silky, clingy emulsion that binds effortlessly to the soft potato dumplings.

Step-by-Step Instructions
1.The Flash Gnocchi Boil:3 min.
Bring a large pot of salted water to a rolling boil. Add 500g (1.1 lbs) of potato gnocchi. Cook for 2 to 3 minutes—as soon as they float to the surface, they are done! Reserve ½ cup of starchy pasta water, then drain the gnocchi.
2.The Garlic & Cream Simmer:2 min.
While the gnocchi boil, melt 1 tablespoon of butter in a large skillet over medium heat. Add 2 minced garlic cloves and sauté for 30 seconds until fragrant. Pour in ½ cup of heavy cream (or half & half) and bring to a gentle simmer for 1 to 2 minutes until slightly reduced.
3.The Pesto & Parmesan Emulsion:2 min.
Lower the heat to low. Stir in ⅓ cup of basil pesto, ⅓ cup freshly grated Parmesan cheese, and 2 to 3 tablespoons of the reserved starchy pasta water. Whisk gently until the cheese melts and forms a smooth, glossy green sauce.
4.The Gentle Toss & Serve:2 min.
Add the cooked gnocchi directly into the skillet sauce. Toss gently for 1 to 2 minutes over low heat until every pillowy dumpling is thoroughly coated in the creamy pesto sauce. Garnish with fresh basil leaves, halved cherry tomatoes, and extra Parmesan, then serve hot!
Expert Tips for Success
- Don’t Overcook the Gnocchi: Watch the pot closely! Gnocchi cook extremely fast; the moment they float to the top of the water, scoop them out or drain them immediately so they don’t become dense or mushy.
- Stir the Pesto in Off/Low Heat: Heating basil pesto too vigorously on high heat can dull its bright green color and cause the oil to separate. Always stir pesto into warm cream over low heat or right off the stove.
- Pan-Fried Variation: Prefer crispy edges? Skip boiling! Sauté the gnocchi directly in a hot skillet with 2 tablespoons of butter for 6–8 minutes until golden and crisp, then pour the warm creamy pesto sauce over top.
