Ingredients You’ll Actually Use

Save

For the shrimp:

• 1.5 pounds large shrimp, peeled and deveined (tail on or off)
• 2 tablespoons olive oil or avocado oil
• 3 cloves garlic, minced
• 1 teaspoon smoked paprika
• 1/2 teaspoon ground cumin
• 1/4–1/2 teaspoon red pepper flakes (optional)
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• Juice of 1/2 lime

For the creamy avocado sauce:

• 2 ripe avocados
• 1/2 cup full-fat sour cream (or Greek yogurt if you’re flexible with carbs)
• 2 tablespoons extra-virgin olive oil
• Juice and zest of 1 lime
• 1 small jalapeño, seeded (optional, for heat)
• 1/4 cup fresh cilantro
• 1 small garlic clove
• 1/2 teaspoon kosher salt, plus more to taste
• 2–4 tablespoons water to thin

To serve (optional but recommended):

• Lime wedges
• Extra cilantro
• Shredded cabbage, arugula, or zucchini noodles

Fast, Foolproof Method

1) Make the sauce: Add avocados, sour cream, olive oil, lime juice and zest, jalapeño, cilantro, garlic, and salt to a blender. Blitz until silky. Add water 1 tablespoon at a time until it’s pourable but still thick.
2) Season the shrimp: Pat shrimp dry (important). Toss with oil, garlic, paprika, cumin, red pepper flakes, salt, and pepper. Squeeze in the lime.
3) Sear like you mean it: Heat a large skillet over medium-high. When hot, add shrimp in a single layer. Cook 1.5–2 minutes per side until just opaque and lightly browned. Don’t overcook unless rubber bands are your thing.
4) Plate it up: Swirl sauce on the plate or toss shrimp in it. Add more cilantro and a squeeze of lime. Serve over shredded cabbage, greens, or zoodles for extra crunch.

Pro Tips So You Don’t Overthink It

• Dry your shrimp. Moisture kills sear and flavor. Paper towels are your friend.
• Use large or extra-large shrimp. They’re juicier and harder to overcook.
• Blend the sauce smooth. If it’s too thick, add water or more lime juice, 1 tablespoon at a time.
• Taste and adjust. More salt or lime can take it from “good” to “wow.”

Flavor Upgrades (Because Boring Food Is a Crime)

Save

• Herb swap: Switch cilantro for basil or parsley if you’re cilantro-averse (it’s genetic, FYI).
• Spice route: Add chipotle powder or a pinch of cayenne to the shrimp rub for smoky heat.
• Umami bump: Finish shrimp with a small pat of butter and a splash of lemon juice.
• Crunch factor: Top with toasted pumpkin seeds or crushed pork rinds for a keto crunch.

Serving Ideas That Keep It Keto

• Over zucchini noodles with cherry tomatoes (halved) and extra lime.
• On a bed of shredded cabbage slaw tossed with lime, olive oil, and salt.
• As lettuce “tacos” using butter lettuce leaves.
• With roasted asparagus or broccolini on the side. Simple wins.

Make-Ahead and Storage

You can blend the avocado sauce up to 24 hours in advance. Press plastic wrap directly onto the surface to limit browning, or stir in an extra splash of lime juice. Keep it chilled.
Cooked shrimp keeps well for 2 days in the fridge. Reheat gently in a skillet over low heat or eat cold. IMO, cold shrimp with that cool, tangy sauce tastes elite.

Freezer Thoughts

Freeze raw shrimp (already peeled and deveined) with the dry seasonings mixed in. Thaw in the fridge overnight, then add fresh lime and oil before cooking. Skip freezing the avocado sauce—it doesn’t love the freezer.

What Makes This Keto-Friendly?

Save

Low net carbs, high fat, and solid protein. Avocado and sour cream deliver satisfying fats without carbs skyrocketing. Shrimp brings protein that won’t weigh you down. The sauce stays low-carb because we skip sugary add-ins and thickening agents.
Also, no starchy sides sneaking in here. If you want volume, pile on leafy greens or non-starchy veg. Your macros will thank you.

FAQ

Can I use frozen shrimp?

Absolutely. Thaw overnight in the fridge or quickly under cold running water. Pat them very dry before seasoning so they sear instead of steam.

Is Greek yogurt okay instead of sour cream?

Yes, but carbs bump slightly and tang increases. If you swap, use full-fat Greek yogurt and taste the sauce—you may want a touch more olive oil and a pinch of salt to balance.

How do I keep the avocado sauce from browning?

Use plenty of lime and press plastic wrap directly on the surface of the sauce. Store in an airtight container. A quick stir before serving brings it back to life.

What veggies go best with this?

Cabbage slaw, zucchini noodles, roasted asparagus, or a simple arugula salad. Keep it crisp and fresh to balance the creamy sauce.

Can I grill the shrimp instead?

For sure. Skewer the shrimp, oil the grates, and grill 1–2 minutes per side over medium-high heat. Same seasoning, same squeeze of lime at the end, same happy dance.

How spicy is it?

Mild by default. Add jalapeño ribs/seeds to the sauce or crank up red pepper flakes if you like a little drama.
