Keto lemon butter shrimp
July 22, 2026 · 3 min read
Lemon butter shrimp hits everything you want in a weeknight dinner: it's fast, it tastes like something you ordered out, and the net carb count is nearly nothing. The combination of butter, garlic, and fresh lemon is simple enough to come together in 15 minutes but rich enough that it doesn't feel like a compromise.
The key to shrimp that actually sears — rather than steams into rubbery little curls — is a dry surface and a hot pan. Pat them well, don't crowd them, and get in and out quickly. Shrimp go from translucent to pink to overdone fast; pull them off the heat as soon as the last bit of translucency disappears.
The lemon zest is worth doing. It adds a brightness that juice alone doesn't quite get, and it keeps the sauce from tasting flat.
Ingredients
- 1.5 lbs large raw shrimp, peeled and deveined
- 4 tablespoons butter
- 4 cloves garlic, minced
- Juice of 1 lemon
- Zest of 1 lemon
- 1/4 teaspoon red pepper flakes
- Small bunch flat-leaf parsley, chopped
- Salt and pepper
- 1 tablespoon olive oil
- Cauliflower rice or zucchini noodles, to serve (optional)
Steps
- Pat the shrimp dry with paper towels and season with salt and pepper.
- Heat the olive oil in a large skillet over medium-high until shimmering.
- Add the shrimp in a single layer. Cook 1–2 minutes per side until pink and just cooked through. Work in batches if needed — don't crowd the pan. Transfer to a plate.
- Reduce heat to medium. Add the butter to the same skillet and let it melt. Add the garlic and red pepper flakes and cook 1 minute until fragrant.
- Stir in the lemon juice and lemon zest. Return the shrimp to the skillet and toss to coat. Cook 30 seconds more.
- Scatter the parsley over the top and serve immediately, over cauliflower rice or zucchini noodles if using.
Notes and swaps
If you can only find medium shrimp, reduce the cook time by about 30 seconds per side. Frozen shrimp works fine here — thaw them in cold water for 10 minutes and dry them well before they go in the pan.
Ghee can replace butter for a slightly nuttier flavor and a higher smoke point. Add capers to the sauce for a sharper, more briny version.
For a low-carb base, keto cauliflower rice is the natural choice — it absorbs the lemony butter sauce well and adds under 4g net carbs per serving. Zucchini noodles are another option if you want something lighter. The shrimp are also good on their own over a simple salad.
This recipe is in the same family as the keto garlic butter salmon — same butter-garlic base, different protein. If you're building a weekly rotation, the keto shrimp stir-fry covers a completely different flavor profile (garlic-ginger, Asian-style) when you want variety.

Leftovers reheat poorly — shrimp gets tough. Cook what you'll eat.
FAQ
Can I use pre-cooked shrimp? You can, but the texture suffers. Pre-cooked shrimp just needs to warm through — 30 seconds in the butter sauce is enough. Don't go longer or they'll tighten up.
Is this recipe dairy-free? Not as written. Swap the butter for ghee (technically dairy but tolerated by many) or use a neutral oil like avocado oil for a fully dairy-free version.
How do I keep the garlic from burning? Pull the pan off medium-high before adding the butter and garlic. The residual heat is enough to cook the garlic in about a minute without scorching it.
What's the net carb count without a side? Just the shrimp with the butter sauce is about 2g net carbs per serving. Cauliflower rice adds roughly 3–4g depending on portion size.
