Keto Chili Lime Shrimp in Garlic Butter (20-Minute Skillet)

Keto chili lime shrimp is a fast, bright, garlicky dinner that takes about 20 minutes from start to finish. Juicy shrimp are tossed in warm chili-lime butter, with smoked paprika for depth and just enough heat to wake up the sauce. No breadcrumbs, sugary glaze, or special keto products needed.

This one-pan meal is naturally low in carbohydrates and easy to adjust. Serve it with cauliflower rice, a simple green salad, or buttery sautéed cabbage to catch every drop of the sauce.

Keto Chili Lime Shrimp at a Glance

• Prep: 10 minutes
• Cook: 10 minutes
• Total: 20 minutes
• Yield: 4 servings

• Flavor: Buttery, tangy, mildly smoky, with adjustable spice

Ingredients

For 4 servings, you will need:

• 1½ lb (680 g) large raw shrimp, peeled and deveined (tails optional)
• 1 tbsp extra-virgin olive oil
• 3 tbsp unsalted butter, divided
• 4 garlic cloves, finely minced
• 2 tbsp freshly squeezed lime juice (about 1 lime), plus 1 tsp finely grated lime zest
• 1 tsp mild chili powder (a ground spice blend without added sugar)
• ½ tsp smoked paprika
• ¼ tsp ground cumin
• ¼ tsp crushed red pepper flakes, optional
• ½ tsp kosher salt, or to taste
• ¼ tsp freshly ground black pepper
• 2 tbsp chopped fresh cilantro or parsley, to finish

For best results, use raw shrimp rather than precooked shrimp. If using frozen shrimp, thaw in the refrigerator and pat very dry so they sear instead of steaming.

How to Make Keto Chili Lime Shrimp

Save

1. Mix the spices. In a small bowl, combine chili powder, smoked paprika, cumin, red pepper flakes (if using), salt, and black pepper. Pat the shrimp thoroughly dry and toss with the spice mix.
2. Sear the shrimp. Heat olive oil and 1 tablespoon of the butter in a large skillet over medium-high heat. Add shrimp in one layer, working in two batches if needed. Cook roughly 1–2 minutes per side until pink and turning opaque, then transfer to a plate. Avoid crowding the pan.
3. Make the garlic butter. Lower the heat to medium-low. Add the remaining 2 tablespoons of butter and the minced garlic. Stir for about 30 seconds, just until fragrant. Do not let the garlic brown.
4. Finish with lime. Turn off the heat. Stir in lime juice and zest, then return the shrimp and any juices to the pan. Toss for 30–60 seconds until evenly coated. Shrimp should be pearly-opaque and firm; avoid overcooking.
5. Serve right away. Sprinkle with cilantro or parsley. Taste before adding more salt or lime. Spoon the sauce over each portion.

Easy Tips for Tender Shrimp

• Dry the surface: Water on the shrimp prevents browning.
• Use a hot pan, not a crowded one: Cook in batches if your shrimp overlap.
• Add lime juice after turning off the heat: This keeps the sauce bright and lowers the chance of the butter splitting.
• Watch the texture: Shrimp quickly go from tender to rubbery when left on the heat too long.
• Choose chili powder carefully: Some premixed seasonings contain added sugar or starch, so check the label.

What to Serve with Chili Lime Shrimp

For a filling keto-friendly plate, serve the shrimp over cauliflower rice with sautéed zucchini or shredded cabbage. A crunchy romaine salad with avocado also works beautifully. If you like seafood with vegetable noodles, try our keto zucchini noodle shrimp scampi next time.

Variations and Substitutions

• Milder: Skip the red pepper flakes and use a mild chili powder.
• Extra smoky: Add a little more smoked paprika, but keep it subtle so it does not overpower the lime.
• Dairy-free: Replace butter with extra olive oil. The finished sauce will be lighter and less creamy.
• Different herbs: Parsley works if you do not enjoy cilantro.
• Meal-prep variation: Cook the cauliflower rice separately so it does not soak up all the sauce before serving.

Storage and Reheating

Refrigerate leftovers in a sealed container within two hours and eat within 3–4 days. Reheat gently in a skillet over low heat, just until hot; prolonged reheating makes shrimp tough. Freeze only if needed, since the texture may change after thawing. Do not leave cooked seafood at room temperature for extended periods.

Frequently Asked Questions

Is this keto chili lime shrimp spicy?

Only mildly when made without red pepper flakes. To increase the heat, add a small pinch of cayenne to the spice mix.

Can I use cooked shrimp?

Yes, but skip the initial sear. Gently warm already-cooked shrimp in the finished garlic-lime butter just until heated through, so they do not turn rubbery.

Can I make it with bottled lime juice?

Fresh lime is best because the zest adds much of the aroma. Bottled juice works in a pinch, but the final flavor is less vivid.
