Ingredient Notes

The Method for Creamy Spinach Pasta Sauce

Step 1: Cook the Pasta
Begin by boiling a large pot of salted water. Add your fettuccine or spaghetti and cook according to the package instructions until al dente. Reserve about 1 cup of pasta water, then drain the pasta and set it aside.
Step 2: Sauté the Garlic
In a large skillet, heat the olive oil over medium heat. Add the finely chopped garlic and sauté for about 1-2 minutes, or until fragrant. Be careful not to burn the garlic, as it can become bitter.
Step 3: Add the Spinach
If using fresh spinach, add it to the skillet and sauté until wilted, about 3-5 minutes. For frozen spinach, add the puree directly to the skillet and stir until heated through.
Step 4: Create the Creamy Base
Pour in the dairy-free cream and stir to combine with the spinach and garlic. Allow it to simmer gently for a few minutes, letting the flavors meld together.
Step 5: Add Nutritional Yeast
Stir in the nutritional yeast and season with salt and pepper to taste. If the sauce is too thick, add a splash of the reserved pasta water until you reach your desired consistency.
Step 6: Combine with Pasta
Add the cooked pasta to the skillet and toss to coat evenly with the creamy spinach sauce. If needed, add more reserved pasta water to help the sauce adhere to the pasta.
Step 7: Serve and Enjoy
Divide the pasta among plates and enjoy immediately. You can garnish with additional nutritional yeast or a sprinkle of black pepper for extra flavor.
Dietary Swaps & Alternatives

- Pasta: Use whole wheat, gluten-free, or legume-based pasta for a healthier twist.
- Dairy-free cream: Substitute with cashew cream or coconut milk for different flavor profiles.
- Nutritional yeast: If you prefer, you can use grated vegan Parmesan for a similar cheesy taste.
- Garlic: Garlic powder can be used in a pinch, though fresh garlic is recommended for the best flavor.
What Could Go Wrong
- Burning the garlic: Keep an eye on the garlic as it cooks, as it can turn bitter if overcooked.
- Too thick of a sauce: If your sauce is too thick, simply add a bit more reserved pasta water to loosen it up.
- Overcooking the pasta: Be sure to follow the package instructions for cooking time to avoid mushy pasta.
- Not seasoning enough: Taste and adjust the seasoning as you go; don’t be afraid to add more salt and pepper.
Save for Later: Storage Tips
If you have any leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm the pasta sauce on the stovetop over low heat, adding a splash of water or dairy-free cream to restore its creamy texture. This creamy spinach pasta sauce also freezes well; just make sure to let it cool completely before freezing in portions. When ready to eat, thaw overnight in the fridge and reheat as directed.
