Creamy pesto pasta is my trick for turning a busy weeknight into something comforting and special. The silky sauce drapes every strand of pasta in garlicky basil goodness. It is fast filling and elegant enough for last-minute company or when you simply need a taste of summer on your plate.
I remember whipping this up after a long workday with just a few things in the fridge and pantry. One bite in and my whole family was gathered at the table laughing and reaching for seconds.
Ingredients
- Pasta of choice: It is best to use short shapes like penne or fusilli for maximum sauce cling. Choose bronze-cut dried pasta for a slightly rougher surface.
- Butter: Adds creaminess and gloss Use real butter for rich flavor.
- Basil pesto: This is the soul of the dish Homemade is wonderful but store-bought works if you pick one with lots of olive oil and a fresh basil aroma.
- Milk or cream: For a saucy texture and balance Cream will make this ultra indulgent while milk keeps it lighter.
- Salt and pepper: Essential for seasoning Taste and adjust just before serving.
- Parmesan cheese: Grated fresh for finishing Aged Parmigiano brings savory nuttiness and a bit of salty depth. Skip the pre-shredded tubs and grate it yourself for the best texture.
Instructions
- Boil the Pasta:
- Cook your pasta in a large pot of salted water until just al dente This brings out the fullest flavor and makes sure your pasta will hold up in the sauce Drain but save about a quarter cup of the pasta water for adjusting the sauce later.
- Make the Pesto Sauce Base:
- In a roomy skillet or pot melt the butter on medium heat Add your pesto and whisk gently You want the mixture to start bubbling a bit but not brown This step opens up the fragrance of the basil.
- Create the Creamy Sauce:
- Turn the heat down to medium low and slowly whisk in your milk or cream Add it gradually to fully blend with the pesto and butter For a silkier sauce warm the milk or cream a bit before adding.
- Combine Pasta and Sauce:
- Add your drained pasta straight into the skillet with the sauce Toss gently and make sure every piece gets coated. Add a splash of reserved pasta water if the sauce seems too thick.
- Serve It Up:
- Pile the coated pasta onto each plate Sprinkle with a heap of freshly grated Parmesan. Toasted pine nuts are a classic finishing touch but not required.

My favorite part of this recipe is the fresh basil pesto It reminds me of my grandmother’s tiny garden where she would pluck basil right before dinnertime Sometimes I add extra just for the heady aroma that fills the kitchen.
