Creamy garlic Parmesan pasta in a rich, cheesy sauce is a quick vegetarian dinner the whole family devours. Simple, indulgent, and ready in 20 minutes for those busy weeknights.
Bring a large pot of salted water to a boil over high heat. Add the spaghetti and cook until al dente, 8–10 minutes.
While pasta cooks, melt butter in a large skillet over medium heat. Add minced garlic and sauté for 1–2 minutes until fragrant but not browned.
Reduce heat to medium-low and pour in heavy cream. Stir and let the mixture heat gently for 2–3 minutes, without letting it boil.
Add grated Parmesan cheese to the skillet in batches, stirring continuously. Keep the heat low to ensure the cheese melts smoothly and the sauce becomes creamy.
Drain the cooked pasta, reserving 1/2 cup of pasta water. Toss the pasta into the skillet with the sauce and use reserved water to adjust creaminess; season with salt, black pepper, and finish with chopped parsley. Serve immediately.
