Ingredients

12 oz (340g) linguine, fettuccine, or spaghetti
1 lb (450g) large shrimp, peeled and deveined
2 large ripe avocados, pitted and scooped
4 Tbsp unsalted butter, divided
3-4 cloves garlic, minced
Juice and zest of 2 lemons (about ¼ cup juice)
2 Tbsp extra virgin olive oil
Salt and black pepper, to taste
½-1 cup reserved pasta cooking water
Optional: ¼ tsp red pepper flakes, ¼ cup grated Parmesan, fresh parsley or basil for garnish

Instructions

Boil that pasta water! Bring a large pot of generously salted water to a rolling boil—salt it well so the pasta tastes amazing from the start.
Cook the pasta al dente. Add pasta and cook per package directions until tender with a slight bite. Reserve 1 cup starchy pasta water, then drain.
Prep the creamy star. While pasta cooks, scoop avocado flesh into a bowl. Mash with a fork until mostly smooth (or blend for silkier texture)—set aside.
Sear the shrimp golden. Heat 1 Tbsp olive oil and 1 Tbsp butter in large skillet over medium-high. Pat shrimp dry, season with salt/pepper, add to pan in single layer. Cook 1-2 minutes per side until pink and curled—remove to plate.
Build the luscious sauce. In same skillet, reduce heat to medium. Add remaining butter, minced garlic, and optional red pepper flakes; sauté 1 minute until fragrant (don't burn garlic!).
Brighten with lemon. Pour in lemon juice and zest, stirring to deglaze pan and create glossy sauce—simmer 1-2 minutes to meld flavors.
Combine with avocado magic. Remove skillet from heat. Stir mashed avocado into lemon-butter sauce until creamy and incorporated—add splashes of reserved pasta water to loosen into silky consistency.
Bring shrimp back. Return cooked shrimp to skillet with sauce; toss gently to warm through and coat.
Toss in the pasta. Add drained pasta to skillet; toss everything together over low heat, adding more pasta water as needed until sauce clings beautifully and everything's glossy.
Finish and feast! Taste—adjust salt, pepper, or lemon. Plate immediately, sprinkle with optional Parmesan and fresh herbs, and dive into this creamy, zesty, buttery delight—pure seafood heaven!

Notes

Avocado browns quickly—mash/add fresh and serve soon for best color. Use fresh lemon for brightest flavor. Shrimp overcooks easily—err on shorter side. Naturally adaptable to dairy-free/gluten-free with swaps.

Recipe Tips and Tricks

Use large, peeled, deveined shrimp for quick cooking—pat dry for better sear and flavor. Don’t overcook shrimp (they turn rubbery)—cook just until pink and curled. Mash or blend avocado right before adding to prevent browning; lemon juice helps preserve color.

Reserve pasta water generously—starchy liquid emulsifies the sauce into silky perfection. Use real butter (not margarine) for authentic richness. Sauté shrimp in the same pan as the sauce for layered flavor.

Taste sauce before tossing—adjust lemon, salt, or pepper boldly. For extra brightness, add lemon zest at the end. Serve immediately while warm for creamiest texture; if sauce thickens, loosen with hot pasta water.

Ingredients Notes

Large shrimp (peeled and deveined) bring sweet, briny seafood flavor and juicy texture—choose fresh or thawed wild-caught for best taste and quick cooking. Ripe avocados provide the creamy, luxurious element—Hass variety mashes smoothly and adds healthy fats that mimic dairy richness without heaviness.

Unsalted butter creates the classic silky, rich base of the sauce—real butter adds depth that oil alone can’t match. Fresh garlic delivers pungent, aromatic warmth essential to lemon-butter sauces. Lemon (juice and zest) is non-negotiable for bright acidity that balances butter and enhances shrimp/avocado.

Pasta like linguine, fettuccine, or spaghetti holds the glossy sauce well. Extra virgin olive oil for searing adds fruity notes, while salt, black pepper, and optional red pepper flakes season and add subtle heat. Fresh parsley or basil brings herbal freshness; Parmesan (optional) adds nutty umami.

Variations and Substitutions

Make it dairy-free by swapping butter for vegan butter or olive oil (sauce less rich but still delicious) and skipping Parmesan or using nutritional yeast. Add veggies like asparagus, cherry tomatoes, spinach, or zucchini—sauté with shrimp.

For gluten-free, use chickpea or rice pasta. Swap shrimp for scallops, chicken, or tofu for different proteins. Amp up heat with more red pepper flakes, chili oil, or diced jalapeños. Use lime instead of lemon for tropical twist.

For richer sauce, blend avocado with a splash of cream or cashew milk. Add sun-dried tomatoes or capers for briny punch. Turn it lighter by reducing butter and adding more lemon juice/pasta water. For pesto flair, blend basil into avocado. Make it cold pasta salad by chilling and tossing with extra veggies.

Storage Options

Best fresh—avocado browns and sauce loses creaminess over time. Store leftovers in airtight container in fridge up to 1 day; press plastic wrap on surface or add extra lemon juice to slow oxidation.

Reheat gently on low stovetop with splash of water/milk to loosen—avoid high heat/microwave to prevent shrimp toughness or bitterness. Not ideal for freezing—avocado texture turns grainy/separates, shrimp toughens.
