Ingredients Overview
Each ingredient in this dish contributes to the vibrant, savory character of a creamy pesto sauce.
Main Ingredients:
-
Pasta (12 oz)
Short pasta like penne, fusilli, or farfalle works best — they hold the sauce beautifully. Use gluten-free or whole wheat if preferred. -
Basil Pesto (½ cup)
Homemade or store-bought. It should include fresh basil, Parmesan, garlic, olive oil, and pine nuts. If using store-bought, choose one refrigerated or high-quality jarred version. -
Heavy Cream (1 cup)
For a rich, velvety sauce. Half-and-half works as a lighter alternative. -
Parmesan Cheese (½ cup, grated)
Melts into the sauce and adds salty, nutty depth. -
Garlic (2 cloves, minced)
Intensifies the savory flavor of the sauce. -
Olive Oil (1 tbsp)
Helps sauté the garlic and marry the pesto and cream. -
Vegetable or Chicken Broth (2½ cups)
Used to cook the pasta directly in the pot and adds extra flavor. -
Salt & Fresh Cracked Black Pepper
To season and balance the dish.
Optional Add-ins:
-
Baby spinach or kale (1 cup) – for greens
-
Sundried tomatoes or cherry tomatoes – for brightness
-
Grilled chicken or shrimp – for added protein
-
Red pepper flakes (¼ tsp) – for a subtle kick
Step-by-Step Instructions
1. Sauté the Garlic
-
In a large, deep skillet or Dutch oven, heat 1 tbsp olive oil over medium heat.
-
Add minced garlic and cook for 30–60 seconds until fragrant, being careful not to burn it.
2. Add Liquids and Pasta
-
Pour in:
-
2½ cups vegetable or chicken broth
-
1 cup heavy cream
-
½ tsp salt and a pinch of black pepper
-
-
Stir and bring to a low boil.
-
Add 12 oz uncooked pasta. Stir to distribute evenly.
3. Simmer Pasta
-
Reduce heat to medium-low and simmer uncovered for 10–12 minutes, stirring often so the pasta doesn’t stick.
-
If sauce thickens too quickly, add ¼ cup more broth or water as needed.
Tip: The pasta will cook in the liquid, releasing starch that helps thicken the sauce naturally.
4. Stir in Pesto and Cheese
-
Once the pasta is tender and the liquid is mostly absorbed, turn off the heat.
-
Stir in:
-
½ cup basil pesto
-
½ cup grated Parmesan cheese
-
-
Mix until the sauce is glossy and creamy.
5. Optional Add-ins and Serve
-
Stir in spinach or kale until wilted (if using).
-
Top with more Parmesan and freshly ground black pepper.
-
Serve immediately while hot.
Tips, Variations & Substitutions

Tips for Success:
-
Use freshly grated Parmesan — pre-shredded won’t melt as smoothly.
-
Stir pasta frequently while simmering to prevent clumping or sticking.
-
Add pesto off the heat to keep the basil flavor fresh and green.
Variations:
-
Protein Add-ins: Grilled chicken, shrimp, or sausage slices make it heartier.
-
Vegetarian Boost: Add roasted cherry tomatoes, mushrooms, or artichokes.
-
Spicy kick: A pinch of red pepper flakes or a swirl of Calabrian chili paste.
Substitutions:
-
Cream: Use half-and-half or full-fat coconut milk for a dairy-free option.
-
Pasta: Gluten-free or lentil-based pastas work well with slightly adjusted cook time.
-
Pesto: Try arugula pesto, sun-dried tomato pesto, or vegan pesto.

FAQs
Q1: Can I make this ahead of time?
A1: It’s best fresh, but leftovers reheat well. Add a splash of broth or cream when reheating to loosen the sauce.
Q2: Can I freeze creamy pesto pasta?
A2: It’s not ideal — the cream may separate when thawed. Store in the fridge for up to 3 days instead.
Q3: What’s the best store-bought pesto?
A3: Look for refrigerated pesto made with real ingredients like Rao’s, Gotham Greens, or Costco’s Kirkland brand. Avoid shelf-stable versions with preservatives.
Q4: How can I make this dairy-free?
A4: Use coconut milk or a plant-based cream, dairy-free pesto (no Parmesan), and nutritional yeast instead of cheese.
Q5: Can I add raw chicken to cook with the pasta?
A5: It’s better to cook chicken separately to avoid undercooked meat. Sear diced chicken beforehand, then add it back at the end.
Q6: Will the pasta be too soft if cooked in the sauce?
A6: Not if you stir frequently and simmer gently. Cook until just al dente for the best texture.
Q7: Can I make this without cream?
A7: Yes! Use a combination of broth and more pesto, or add a spoonful of Greek yogurt at the end for tangy creaminess.
