A quick and creamy crème fraiche pasta recipe made with smoky bacon, sweet peas, lemon zest, and Parmesan cheese. An easy 30-minute weeknight pasta dinner.
Cook pasta to al dente, according to package instructions, in salted water. During the last minute of cooking, add frozen peas. Reserve 1 cup of pasta water before draining.
Trim and thinly slice green onions on the diagonal and chop the bacon. Set a side a few of each to garnish the finished dish.
In a large skillet, heat olive oil over medium-high heat. Add the chopped green onions and season with salt and pepper. Cook, stirring occasionally, for 2 to 3 minutes. Add the bacon, minced garlic, and red pepper flakes. Continue to cook until the bacon is done and the green onions are beginning to brown and char; about 6 to 7 minutes total.
While the pasta is cooking, make the sauce. In a large bowl, combine the Parmesan, creme fraiche, and lemon zest; stir to combine. Then stir in ½ cup of reserved pasta water until the sauce is smooth and creamy. Season with salt and pepper and stir in the green onions and bacon mixture.
Once the pasta and peas are cooked. Add the pasta to the sauce; toss until fully combined. Add additional pasta water if desired to loosen the sauce.
Notes
Salt the pasta water well. Properly salted water helps season the pasta from the inside and makes the finished dish more flavorful.
Reserve the pasta water. The starchy pasta water helps loosen the crème fraîche sauce and allows it to coat the pasta smoothly.
Don’t overheat the crème fraîche. Stir it into the pasta off the heat or over very low heat to maintain its silky texture.
Use freshly grated Parmesan. Pre-shredded cheese doesn’t melt as smoothly and can affect the sauce texture.
Pasta options: Orecchiette works beautifully because it catches the sauce, but shells, penne, or rigatoni are great alternatives.
Substitute for crème fraîche: Sour cream can be used in a pinch. For best results, stir it off the heat to prevent curdling.
Make it vegetarian: Omit the bacon and sauté sliced mushrooms instead for a savory alternative.
Leftovers: Store leftovers in the refrigerator for up to 2 days. Reheat gently with a splash of milk or pasta water to loosen the sauce.
