Tender garlic-butter shrimp with a bright lemon-dill cream sauce over roasted cauliflower rice — a naturally keto dinner ready in about 25 minutes. The shrimp sear in foaming butter until just opaque (overcooking by 30 seconds is what turns shrimp rubbery, so pull when the curl is loose-not-tight), then a quick lemon-dill cream pan sauce builds in the same skillet while the cauliflower rice steams its excess moisture off. Pair with a simple green salad or roasted asparagus — a complete low-carb dinner for two without a second pan.

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Spread 2 cups cauliflower rice on a parchment-lined baking sheet, drizzle with 1 tbsp olive oil, and season with 1/4 tsp salt and 1/8 tsp black pepper; roast for 15 minutes until golden and tender, stirring once halfway.
  2. Step 2: While cauliflower roasts, heat 1 tbsp olive oil and 1 tbsp unsalted butter in a large skillet over medium-high heat. Add 3 minced garlic cloves and sauté for 60 seconds until fragrant, then add 12 oz peeled shrimp and cook for 2 minutes per side until pink and opaque.
  3. Step 3: Stir in 1/4 cup heavy cream, 1 tbsp lemon juice, 2 tbsp fresh dill, and 1/4 tsp salt; simmer for 2 minutes until sauce thickens slightly and coats the back of a spoon, then remove from heat.
  4. Step 4: Gently fold roasted cauliflower rice into the shrimp mixture until evenly coated, adjusting salt and pepper to taste, and serve immediately while hot.

Frequently asked questions

Is this recipe truly keto-friendly?

Yes — every component is keto-compliant by design. Shrimp is naturally zero-carb protein. Butter and heavy cream are pure fat with no added sugar. Cauliflower rice replaces grain-based rice with a cruciferous vegetable that runs roughly 3g net carbs per cup. Fresh lemon, dill, and garlic add flavor without measurable carbs. The total dish lands at 6–8g net carbs per serving, comfortably inside a strict 20g/day ketogenic target. No keto-banned ingredients (flour, breadcrumb, sweeteners, starchy thickeners) appear anywhere in the recipe.

How many net carbs per serving?

About 6–8g net carbs per serving (one quarter of the recipe), with the cauliflower rice accounting for almost all of it. Net carbs are calculated as total carbohydrates minus fiber: cauliflower rice contributes roughly 5g total carbs and 2g fiber per cup, the heavy cream adds ~1g, and the garlic, lemon, and dill round out the remainder. Shrimp and butter contribute zero. Exact macros vary 1–2g depending on shrimp size and how much cauliflower rice you portion per plate.

Can I use frozen cauliflower rice?

Yes, with one timing change. Frozen cauliflower rice releases more water than fresh as it thaws, so add an extra 2–3 minutes uncovered to drive off the excess moisture — otherwise the sauce thins out and the rice turns mushy. The fastest method: skip the thaw, dump the frozen rice straight into a hot dry skillet, cover for 3 minutes to steam, then uncover and cook another 4–5 minutes stirring occasionally to evaporate residual water. Season at the end, after the moisture is gone, so the salt level reads correctly.

What can I substitute for heavy cream on keto?

For the lemon-dill cream sauce, the two best keto-safe substitutes are full-fat coconut cream (use ¾ the volume — coconut cream is thicker) or full-fat unsweetened Greek yogurt added off-heat at the very end so it does not split. Half-and-half is NOT a like-for-like swap on strict keto: at ~10g carbs per cup it can push the dish out of net-carb range. Avoid evaporated milk, condensed milk, and any "light" cream products entirely — they carry added carbs and often sweeteners.

How do I store and reheat leftover keto shrimp?

Cool completely and store in an airtight container in the refrigerator for up to 3 days. Reheat gently in a covered skillet over low heat with a splash of cream or water — 4–6 minutes, stirring once. Microwaving works but turns the shrimp rubbery: if you must microwave, use 50% power in 30-second bursts and stop the moment the dish is warm through. Do not freeze: cream-based sauces split on thaw and cauliflower rice turns watery. The dish reheats best the next day; by day three the dill flavor fades, so plan accordingly.
