Notes
🥡 STORAGE: Store leftovers in an airtight container in the refrigerator for up to 3 days.Store the sauce separately from the pasta when possible for the best texture.♨️ REHEATING: Reheat gently on the stovetop over low heat with a splash of cream, milk, or broth.Microwave in 30-second intervals, stirring between each interval until heated through.❄️ FREEZING: Freezing is not recommended because the cream sauce may separate after thawing.💡 TIPS FOR BEST RESULTS: Roast the peppers until nicely blistered for the best smoky flavor.Blend the sauce completely smooth for a silky texture.Salt the pasta water generously for better flavor throughout the dish.🍳 ALTERNATE COOKING METHODS: Roast the peppers directly over a gas burner or a grill, rather than broiling.Bake the finished pasta in a casserole dish topped with cheese for a baked pasta variation.♻️ LEFTOVERS: Use leftovers as a filling for stuffed peppers.Add grilled chicken or shrimp for a second meal variation.Toss leftovers with extra cheese and bake into a creamy pasta casserole.📝 NOTES: Poblano peppers can vary in heat level, so taste before adding additional peppers.Cotija cheese or feta cheese can be substituted for queso fresco.Fresh parsley can be used instead of cilantro if preferred.
