Silky cauliflower grits, kissed with aged cheddar and a whisper of nutmeg, become the perfect throne for glistening shrimp that have been seared in foaming lemon-garlic butter. One bite and youâll swear youâre in Charlestonâonly without the carb coma. I created this dish after a beach-house vacation where the only thing better than the sunset was the seafood, but I needed a keto-friendly way to keep the memory alive. Now itâs our standing Friday-night tradition: skillet on the stove, jazz on the speaker, and these outrageously juicy shrimp that cook in five minutes flat. Whether youâre feeding carb-conscious guests or simply craving comfort without the post-pasta slump, this recipe delivers restaurant-level luxury with everyday ease.
Why This Recipe Works
- One skillet + one saucepan: Minimal cleanup while the grits simmer and the shrimp sizzle.
- Restaurant-quality sear: Pat-dry shrimp + scorching-hot pan = caramelized edges without overcooking.
- Creamy without carbs: Cauliflower rice transforms into velvety grits with help from grass-fed butter and sharp cheddar.
- Bright, bold flavor: Lemon zest + juice balance the richness; garlic infuses the butter for aromatic depth.
- Meal-prep hero: Grits reheat like a dream; shrimp cook fresh in 4 minutes for office lunches that feel like dine-out.
- Macro-friendly: 6 g net carbs, 28 g protein, and a sat-fat profile that keeps ketones happy.
Ingredients You'll Need
Great seafood begins at the fish counter. Look for wild-caught Gulf or Atlantic shrimp that smell like the ocean, not ammonia. I buy 16/20 count because theyâre meaty yet quick-cooking; smaller shrimp work, but reduce the sear time by 30 seconds per side. For the cauliflower, grab pre-riced if youâre pressed for time, though pulsing florets in a food processor yields fluffier âgrits.â The secret to creamy texture is a blend of cream cheese and freshly grated sharp cheddarâpre-shredded cellulose-coated cheese wonât melt as silkily. Finally, choose grass-fed butter for its higher omega-3s and that unmistakable golden hue.

How to Make Keto Lemon Garlic Butter Shrimp with Cauliflower Grits
Pat shrimp very dry
Excess moisture = steam, not sear. Spread shrimp on a triple layer of paper towels, top with more towels, and press firmly. Transfer to a bowl; season with salt, pepper, paprika, cayenne, and lemon zest. Toss to coat and let stand 10 minutes while you start the grits.
SautĂŠ cauliflower rice
Heat olive oil in a medium saucepan over medium. Add cauliflower rice and a pinch of salt; cook 4 minutes, stirring, until it begins to turn golden but is still crisp-tender. This step drives off moisture and builds nutty flavor.
Simmer into grits
Stir in chicken broth; bring to a gentle boil. Reduce heat to low, cover, and simmer 6 minutes, stirring once halfway. The cauliflower should be soft and most of the liquid absorbed. If it dries out, splash in 1 Tbsp broth at a time.
Enrich with cheese
Reduce heat to the lowest setting. Vigorously stir in cream cheese until melted, then fold in cheddar, heavy cream, and nutmeg. Season with salt and white pepper. Cover and keep warm while you sear the shrimp; stir occasionally so a film doesnât form.
Heat the skillet
Place a large stainless or cast-iron skillet over medium-high heat until a drop of water dances across the surfaceâabout 2 minutes. Add 1 Tbsp butter; swirl until the foaming subsides and the butter just begins to brown. You want sizzle, not smoke.
Sear shrimp 1½ minutes
Add half the shrimp in a single layer, presentation-side down. Do not crowd; work in batches if necessary. Let them cook undisturbed until edges turn pink and centers are opaqueâabout 90 seconds. Flip; cook 30â45 seconds more. Transfer to a warm plate and tent loosely.
Build lemon-garlic butter
Reduce heat to medium-low. Add remaining 3 Tbsp butter to the hot skillet. Once melted, add garlic; sautĂŠ 20 seconds until fragrant but not browned. Stir in lemon juice, scraping the browned bits. Return all shrimp; toss 30 seconds to glaze.
Plate and finish
Spoon a mound of creamy cauliflower grits into shallow bowls. Nestle shrimp on top; drizzle with the lemon-garlic pan sauce. Scatter parsley and a pinch of red-pepper flakes for color. Serve immediately with extra lemon wedges.
Expert Tips
De-veining hack
Snip along the outer shell with kitchen shears, then lift the vein in one swift pullâshell stays on for presentation and flavor.
Temp check
Shrimp finish cooking in the sauce; pull them at 120 °F for perfect curlâtight âOâ shapes mean over-cooked.
Ice-bath trick
If prepping ahead, shock cooked shrimp in ice water for 30 seconds to stop carryover cooking, then re-warm gently in butter.
Nutmeg nuance
A pinch of nutmeg amplifies cheese flavor without being identifiableâclassic French bĂŠchamel wisdom applied to low-carb grits.
Double-duty butter
Brown the butter for 60 seconds before garlic for nutty depth, but watch closelyâclarified solids burn fast.
Make it dairy-free
Swap butter for ghee and use coconut cream plus nutritional yeast instead of cream cheese/cheddarâstill keto, still luscious.
Variations to Try
-
Cajun kick
Replace paprika with 1 tsp Cajun seasoning and add diced andouille sausage to the grits for smoky heat.
-
Herb garden
Fold in fresh tarragon and chives at the end for springtime brightness that plays beautifully with lemon.
-
Sun-dried tomato
Stir 2 Tbsp finely chopped oil-packed sun-dried tomatoes into the grits for umami and color.
-
Seafood medley
Add seared sea scallops or lump crabmeat during the final butter toss for an extra-special surf-and-surf.
Storage Tips
Refrigerate: Cool grits and shrimp separately in airtight containers up to 3 days. Reheat grits with a splash of broth in a saucepan over low, stirring until creamy. Warm shrimp in a non-stick skillet with a dab of butter just until heatedâabout 90 secondsâto avoid rubbery texture.
Freeze: Freeze grits (without shrimp) in freezer-safe bags, pressed flat, for up to 2 months. Thaw overnight in the fridge and reheat as above. I donât recommend freezing cooked shrimp; they become tough.
Make-ahead: Prep the cauliflower rice and chop garnishes up to 4 days ahead. You can also marinate the shrimp (minus lemon juice) 8 hours prior; add juice just before cooking so acid doesnât start curing the flesh.
