The problem: you want a creamy, comforting pasta dish but you're trying to eat more vegetables and less heavy cream. Most creamy pasta recipes rely on butter and heavy cream, which can leave you feeling sluggish. This recipe solves that by using ripe avocado and spinach to create a silky, nutrient-dense sauce that doesn't skimp on flavor.

The solution: a quick 25-minute pasta dish where the sauce comes together in the blender while the pasta cooks. The avocado provides healthy fats and creaminess, while the spinach adds a pop of green and a boost of iron. The cheese—I use sharp cheddar for tang, but you can swap in parmesan or a dairy-free alternative—melts into the sauce for that indulgent, cheesy finish.
This is a one-pot meal if you use the same pot for pasta and sauce (just drain and return). It's perfect for a weeknight when you want something satisfying but not heavy. Let's get started.
Why You'll Love This Recipe
About the Ingredients
12 oz (340g) whole wheat penne or your favorite pasta
Whole wheat adds fiber and nutty flavor. Substitute with gluten-free pasta if needed; adjust cooking time per package.
2 ripe avocados, peeled and pitted
Ripe avocados are essential for creaminess. If they're not ripe, the sauce will be lumpy. You can ripen them in a paper bag with a banana.
2 cups (60g) fresh baby spinach, packed
Baby spinach is tender and mild. You can use frozen spinach, but thaw and squeeze out excess water first.
1 cup (100g) shredded sharp cheddar cheese
Sharp cheddar adds a tangy kick. For a milder flavor, use Monterey Jack or a vegan cheddar alternative.
1/2 cup (50g) grated Parmesan cheese
Parmesan adds salty umami. Use a vegetarian-friendly brand or substitute with nutritional yeast for a dairy-free version.
3 cloves garlic, minced
Fresh garlic gives a pungent bite. If you're short on time, use 1 teaspoon garlic powder.
1/4 cup (60ml) olive oil
Olive oil helps emulsify the sauce. Use a good quality extra virgin for best flavor.
1/4 cup (60ml) lemon juice (about 1 lemon)
Lemon juice adds brightness and prevents avocado from browning. Lime juice works too.
1/2 tsp salt, plus more for pasta water
Salt enhances flavors. Use kosher salt for better control.
1/4 tsp black pepper
Freshly ground black pepper adds a mild heat. Adjust to taste.
1/4 cup (60ml) pasta water, reserved
Starchy pasta water helps thin the sauce and make it cling to the pasta.
Tips & Tricks
Use ripe avocados
If they're too firm, they won't blend smoothly. Look for ones that give slightly when pressed.
Don't overcook the pasta
Cook to al dente as it will continue cooking slightly when tossed with the warm sauce.
Reserve pasta water
It helps loosen the sauce to the perfect consistency. Add it gradually until you reach your desired texture.
Pro Tips
Step-by-Step Instructions
1. Cook the pasta
Bring a large pot of salted water to a boil (212°F/100°C). Add pasta and cook according to package directions until al dente, about 8-10 minutes. Reserve 1 cup of pasta water, then drain and return pasta to the pot.
2. Blend the sauce
In a blender, combine avocados, spinach, cheddar, Parmesan, garlic, olive oil, lemon juice, salt, and pepper. Blend on high until smooth, about 1-2 minutes. If too thick, add a splash of pasta water to reach a creamy consistency.
3. Combine and heat
Pour the sauce over the hot pasta in the pot. Stir over low heat (300°F/150°C) for 2-3 minutes until everything is heated through and the cheese is melted. The sauce should be thick and coat the pasta evenly.
4. Adjust consistency
If the sauce is too thick, add reserved pasta water one tablespoon at a time until it reaches your desired consistency. Taste and adjust seasoning with more salt, pepper, or lemon juice if needed.
5. Serve immediately
Divide among bowls and garnish with extra Parmesan, black pepper, or a drizzle of olive oil. Serve hot for the best texture and flavor.
Delicious Variations
Add protein
Toss in cooked chicken, shrimp, or tofu for extra satiety.
Make it spicy
Add 1/2 teaspoon red pepper flakes or a pinch of cayenne to the blender.
Swap greens
Use kale or arugula instead of spinach; blanch kale first to soften.
How to Store Cheesy Avocado Spinach Pasta
Refrigerator
Store in an airtight container for up to 2 days. The avocado may brown slightly, but a squeeze of lemon before storing helps slow oxidation.
Freezer
Freeze in a freezer-safe container for up to 1 month. Thaw overnight in the fridge and reheat gently. Note: texture may change slightly due to avocado.
Reheating
Reheat in a skillet over medium heat (350°F/175°C), adding a splash of water or milk to restore creaminess. Stir frequently to prevent sticking.
Frequently Asked Questions
Q: Can I use frozen spinach instead of fresh?
Yes, but thaw and squeeze out excess water before blending to avoid watery sauce. Use 1/2 cup thawed, squeezed spinach.
Q: How do I keep avocado from browning in the sauce?
The lemon juice in the recipe helps prevent browning. Additionally, store leftovers with a layer of plastic wrap directly on the surface to minimize air exposure.
Q: Can I make this vegan?
Yes, use vegan cheddar and Parmesan substitutes, or nutritional yeast for a cheesy flavor. The rest is already plant-based.
Q: What if I don't have a blender?
You can mash the avocado with a fork and finely chop the spinach, then mix everything together in the pot. The texture will be chunkier but still delicious.
