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.
