Why You’ll Love This

It’s one-pan, super quick, and tastes like restaurant shrimp scampi vibes without the pasta. The lemon brightens everything, the garlic butter sauce is rich but not heavy, and the shrimp stay juicy with minimal effort.

Ingredients

• 1 1/2 lb large shrimp (raw), peeled and deveined (tails on or off)
• 1/2 tsp kosher salt (plus more to taste)
• 1/4 tsp black pepper
• 1/4 tsp smoked paprika (optional, for color and a subtle smoky note)
• 2 tbsp olive oil
• 4 tbsp unsalted butter, divided
• 5–6 garlic cloves, minced
• 1/4 tsp red pepper flakes (optional)
• 1 lemon (zest + 2 tbsp fresh juice, plus wedges for serving)
• 2 tbsp chopped fresh parsley
• 2 tbsp chicken broth or dry white wine (optional, helps loosen the sauce)

How to Make It

1. Pat the shrimp very dry with paper towels. This helps them sear instead of steaming. Season with salt, pepper, and smoked paprika (if using).
2. Heat a large skillet over medium-high heat. Add the olive oil and 2 tablespoons of the butter.
3. Once the butter melts and gets foamy, add the shrimp in a single layer. Cook for 1–2 minutes per side, just until pink and curled. Don’t overcook. Transfer shrimp to a plate.
4. Lower the heat to medium. Add the remaining 2 tablespoons butter to the pan, then stir in the minced garlic and red pepper flakes. Cook for about 30–45 seconds, just until fragrant (garlic burns fast).
5. Add lemon zest, lemon juice, and the chicken broth or wine (if using). Scrape up any browned bits from the pan and simmer for 30–60 seconds to slightly reduce.
6. Return the shrimp (and any juices on the plate) to the skillet. Toss for 30–60 seconds until the shrimp are coated and warmed through.
7. Turn off the heat and sprinkle in parsley. Taste and adjust with a pinch more salt, pepper, or an extra squeeze of lemon if you like it brighter.
8. Serve immediately with lemon wedges and spoon the garlic butter sauce over everything.

Tips for the Best Results

• Dry shrimp = better sear. Moisture is the enemy of browning. Pat them down well before seasoning.
• Use large shrimp. They’re harder to overcook and stay juicy. If using smaller shrimp, reduce cook time.
• Don’t crowd the pan. Cook in two batches if needed so the shrimp actually sear.
• Garlic goes in after the shrimp. If you add it too early, it can burn and taste bitter.
• Lemon zest adds major flavor. Juice is great, but zest gives that fresh lemon “pop” without extra acidity.
• Keep it keto-friendly. Skip flour, breadcrumbs, or sugary marinades. This recipe is naturally low-carb as written.
• Make it a meal. Serve over cauliflower rice, zucchini noodles, or alongside roasted asparagus and a simple salad.

Variations

• Creamy garlic butter shrimp: After step 5, stir in 2–3 tablespoons heavy cream and simmer for 1 minute before adding the shrimp back.
• Parmesan finish: Off heat, toss in 2–3 tablespoons finely grated parmesan for a slightly thicker, savory sauce.
• Herb swap: Try basil, chives, or dill instead of parsley for a different vibe.
• Extra lemony: Add a few thin lemon slices to the pan while the sauce simmers for a pretty, aromatic finish (remove seeds first).
• Spicy version: Double the red pepper flakes or add a pinch of cayenne with the paprika.
• Add veg: Toss in a handful of baby spinach at the end until just wilted, or sauté sliced zucchini in the pan before cooking the shrimp.

Storage & Reheating

Store leftovers in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over low heat with a small pat of butter or splash of broth to loosen the sauce; avoid microwaving too long since shrimp can turn rubbery fast.

FAQ

Can I use frozen shrimp?

Yes—just thaw completely first. The easiest way is to place frozen shrimp in a colander and run cold water over them for 5–8 minutes, tossing occasionally. Pat them very dry before cooking so they sear properly.

How do I know when shrimp are cooked perfectly?

Shrimp are done when they turn opaque and pink and form a loose “C” shape. If they curl into a tight “O,” they’re usually overcooked. Pull them as soon as they’re just done—they’ll finish warming when you toss them back in the sauce.

Is this recipe keto-friendly as written?

Yes. Garlic, butter, lemon, herbs, and shrimp are naturally low-carb. If you add broth or wine, keep it to a small amount and avoid anything with added sugar. Pair with cauliflower rice, zucchini noodles, or roasted veggies for a fully keto dinner.

What can I serve with garlic butter shrimp to keep it low-carb?

Great options: cauliflower mash, cauliflower rice, sautéed zucchini noodles, roasted broccoli, asparagus, or a crisp salad with a simple olive oil vinaigrette. If you want to soak up sauce, keto rolls or chaffles work too.

Can I make the sauce ahead of time?

You can prep components (mince garlic, chop parsley, zest/juice the lemon) ahead, but the sauce is best fresh. If you do make it early, rewarm it gently and cook the shrimp right before serving so the shrimp stay tender and not overcooked.
