Follow these simple, step-by-step instructions to create the perfect Creamy Tomato Basil Gnocchi in under 30 minutes. The process is straightforward, making it ideal for cooks of all skill levels.

1. Start the Sauce Base: Place a large skillet or Dutch oven over medium heat. Add the olive oil and butter. Once the butter has melted and is sizzling, add the finely chopped yellow onion. Sauté for 4-5 minutes, stirring occasionally, until the onion has softened and become translucent.
2. Bloom the Aromatics: Add the minced garlic, dried oregano, and optional red pepper flakes to the skillet. Cook for another minute, stirring constantly, until the garlic is fragrant. Be careful not to let the garlic burn, as it can become bitter. This step is crucial for building a deep flavor profile.
3. Simmer the Tomato Sauce: Pour the can of crushed tomatoes into the skillet. Add the optional sugar, and season generously with salt and black pepper. Stir everything together to combine. Bring the sauce to a gentle simmer, then reduce the heat to low, cover, and let it cook for at least 10-15 minutes. This simmering time allows the flavors to meld and deepen.
4. Cook the Gnocchi: While the sauce is simmering, bring a large pot of salted water to a rolling boil. Add the package of gnocchi to the boiling water. The gnocchi will sink to the bottom at first. Cook according to package directions, typically for 2-4 minutes. You will know they are done when they float to the surface of the water.
5. Finish the Cream Sauce: While the gnocchi is cooking, turn your attention back to the sauce. Uncover the skillet and stir in the heavy cream and grated Parmesan cheese. Continue to stir until the cheese is fully melted and the sauce has turned a beautiful, creamy pink-orange color. Taste the sauce and adjust the seasoning with more salt and pepper if needed.
6. Combine Gnocchi and Sauce: Using a slotted spoon or spider strainer, transfer the cooked gnocchi directly from the boiling water into the skillet with the creamy tomato sauce. The little bit of starchy cooking water that comes with them will help the sauce cling beautifully to each piece.
7. Add Fresh Basil: Gently stir the gnocchi into the sauce to coat every piece. Remove the skillet from the heat and stir in the freshly sliced basil. The residual heat will wilt the basil perfectly without it losing its vibrant color and fresh flavor.
8. Serve Immediately: Divide the Creamy Tomato Basil Gnocchi among bowls. Garnish with extra grated Parmesan cheese, a few more fresh basil leaves, and a final crack of black pepper. Enjoy immediately while warm and delicious.
