Ingredients
Method
- Prep the shrimp and sausage: Pat shrimp very dry with paper towels. Toss shrimp with 1–2 tsp Cajun seasoning, a pinch of salt, and black pepper. Slice the sausage into rounds.
- Heat the skillet: Use a large cast-iron or stainless-steel skillet for best sear. Add 1 tbsp oil over medium-high heat until shimmering.
- Brown the sausage: Add the sliced sausage. Cook 3–5 minutes, flipping occasionally, until browned and slightly crisp. Remove to a plate and keep warm.
- Cook the veggies: In the same skillet, add the remaining 1 tbsp oil. Add onion and bell peppers (and optional zucchini or mushrooms). Season with a pinch of salt, 1 tsp Cajun seasoning, and the smoked paprika. Cook 4–6 minutes, stirring occasionally, until tender-crisp with a bit of char. Transfer to the plate with the sausage.
- Sear the shrimp: Return the skillet to medium-high. Add 1 tbsp butter. When melted and foamy, add shrimp in a single layer. Cook 1–2 minutes per side until just opaque and lightly seared. Don’t overcrowd; cook in batches if needed. Remove shrimp and set aside.
- Build the Cajun butter: Reduce heat to medium. Add the remaining 1 tbsp butter and minced garlic. Sauté 30 seconds until fragrant. Stir in lemon juice and, if you like it spicier, a pinch of cayenne. Taste and adjust salt and Cajun seasoning.
- Combine: Return sausage and veggies to the skillet. Toss to coat in the Cajun butter. Gently fold in the shrimp just to warm through, 30–60 seconds.
- Cook the cauliflower rice: In a separate pan, sauté cauliflower rice with a drizzle of oil and a pinch of salt and pepper over medium heat for 3–5 minutes until hot and tender, not soggy. Optionally season with a light sprinkle of Cajun seasoning.
- Assemble the bowls: Spoon cauliflower rice into bowls. Top with the shrimp, sausage, and veggie mix. Garnish with chopped parsley or green onions. Serve with extra lemon wedges.

Storage Instructions
- Refrigerator: Store the shrimp-sausage mixture and cauliflower rice separately in airtight containers for up to 3 days.
- Reheating: Warm the shrimp-sausage mix gently in a skillet over medium heat just until hot to avoid overcooking the shrimp. Reheat the cauliflower rice in a dry skillet to keep it fluffy.
- Freezer: Freeze the sausage-veggie portion for up to 2 months. Freeze shrimp separately for best texture, or cook fresh shrimp when serving.
- Meal prep tip: Portion into bowls without the garnish.
Add fresh herbs and lemon just before eating to brighten the flavors.
Health Benefits
- Low-carb and keto-aligned: Cauliflower rice keeps carbs minimal while adding fiber and volume.
- High in protein: Shrimp and sausage deliver protein to support satiety and muscle maintenance.
- Healthy fats: Butter and oil help with flavor and absorption of fat-soluble nutrients, keeping energy steady.
- Micronutrients: Bell peppers and onions contribute vitamin C, antioxidants, and potassium.
- Spices with benefits: Paprika, garlic, and cayenne bring anti-inflammatory compounds and big taste with minimal calories.
What Not to Do
- Don’t overcrowd the skillet: Crowding steams the shrimp and sausage and robs you of that golden sear.
- Don’t overcook the shrimp: Rubberiness happens fast. Pull them as soon as they turn pink and opaque.
- Don’t skip drying the shrimp: Excess moisture prevents browning and dilutes the seasoning.
- Don’t rely on sugary spice blends: Some Cajun mixes hide sugar or starch. Read labels or make your own.
- Don’t drown the cauliflower rice: Too much oil or time makes it soggy.
Keep it hot and quick.
Alternatives
- Protein swaps: Use chicken thighs or turkey sausage. For pescatarians, add scallops or swap sausage for more shrimp.
- Veggie variations: Try asparagus, broccoli, or spinach. Keep portions balanced to maintain low net carbs.
- Heat levels: Mild?
Use less Cajun and skip cayenne. Extra hot? Add more cayenne or a few dashes of hot sauce.
- Fats and oils: Substitute ghee for butter or use olive oil if preferred.
- Serving base: Cauliflower rice is classic, but sautéed zucchini noodles or shredded cabbage also work well.
- Dairy-free: Replace butter with more avocado oil or coconut oil, and finish with extra lemon for richness.
FAQ
How spicy is this recipe?
It’s medium by default.
You can make it milder by using less Cajun seasoning and skipping cayenne, or crank it up with extra spice or hot sauce.
Can I use pre-cooked shrimp?
Yes, but add them at the very end just to warm through, 30–60 seconds. Pre-cooked shrimp can turn rubbery if heated too long.
What kind of sausage works best?
Smoked andouille is traditional for that Cajun kick. Kielbasa or any smoked sausage without added sugars is a solid keto-friendly choice.
Can I make this ahead for meal prep?
Absolutely.
Cook everything, store components separately, and reheat gently. Add fresh herbs and lemon right before serving to keep flavors bright.
How do I make my own Cajun seasoning?
Combine paprika, garlic powder, onion powder, dried oregano, dried thyme, black pepper, salt, and a pinch of cayenne. Adjust heat to taste and skip sugar.
Is cauliflower rice necessary?
No.
You can serve the mix over sautéed cabbage, zucchini noodles, or simply enjoy it as a hearty skillet meal on its own.
Can I use frozen shrimp?
Yes. Thaw completely and pat very dry before seasoning. Excess moisture prevents a good sear.
What if I don’t have a large skillet?
Cook in batches to avoid overcrowding.
Keep finished components warm in a low oven while you finish the rest.
