This recipe began on a busy weeknight when I wanted big flavor with minimal fuss. I had smoked sausage in the fridge and a bag of frozen shrimp — a quick sear, a splash of cream, a hit of Cajun spice, and the kitchen smelled like a tiny Southern bistro. What surprised me most was how well the cream and Parmesan softened the heat, creating a silky sauce that still packed personality. It’s since become a family favorite and a go-to when I want to impress without hours in the kitchen.
๐งพ Ingredients (4 servings)
- 1 lb large shrimp, peeled and deveined
- 12 oz smoked sausage or andouille, sliced
- 2 tbsp butter
- 1 tbsp olive oil
- 1 medium red bell pepper, sliced
- 1 small yellow bell pepper, sliced
- 1 small onion, sliced
- 4 cloves garlic, minced
- 1 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 1/4 cup chicken broth (optional)
- 2 tsp Cajun seasoning
- 1/2 tsp smoked paprika
- 1/4 tsp crushed red pepper flakes (optional)
- 2 cups baby spinach
- 2 tbsp chopped parsley (for garnish)
- 1 tbsp lemon juice (optional)
- Salt & black pepper, to taste
๐จ๐ณ Instructions — Step by Step
- Prep the shrimp: Pat shrimp dry with paper towels. Toss with a pinch of salt, black pepper, and 1 tsp Cajun seasoning so they’re lightly coated. Dry shrimp = better sear.
- Brown the sausage: Heat 1 tbsp butter and 1 tbsp olive oil in a large heavy skillet over medium-high heat. Add the sliced sausage and sear until both sides are nicely browned (3–4 minutes). Remove sausage to a plate so it doesn’t overcook.
- Sautรฉ vegetables: In the same skillet, add the remaining 1 tbsp butter. Toss in the sliced onion and bell peppers; cook about 4 minutes until softened and slightly caramelized — these little browned bits add tons of flavor.
- Add aromatics: Stir in the minced garlic and smoked paprika; cook 30 seconds until fragrant but not burnt. Keep the heat moderate — burnt garlic tastes bitter.
- Build the creamy sauce: Pour in the chicken broth to deglaze the pan, scraping up those fond (brown bits). Add heavy cream and bring to a gentle simmer. Reduce heat to medium-low so the cream doesn’t boil.
- Cheese & seasoning: Whisk in grated Parmesan, remaining Cajun seasoning, and crushed red pepper flakes. Stir until the cheese melts and the sauce thickens to a silky consistency (2–3 minutes). Taste and adjust salt and heat.
- Finish with protein: Return the browned sausage to the skillet and add the seasoned shrimp. Cook 2–3 minutes, tossing gently, until shrimp turn pink and are just cooked through — shrimp cook fast, so watch closely.
- Greens & finish: Fold in baby spinach until wilted. Squeeze in lemon juice if using, adjust salt and pepper, and sprinkle with chopped parsley for brightness.
- Serve: Plate over zucchini noodles, cauliflower rice, or a bed of mixed greens. Spoon plenty of sauce over everything and enjoy immediately. Leftovers reheat well but are best within 48–72 hours.
- Don’t crowd the pan when browning sausage or shrimp — sear in batches if needed to get a proper crust.
- Freshly grate your Parmesan — it melts smoother and prevents a grainy sauce.
- If the sauce gets too thick, loosen it with a splash of broth or an extra tablespoon of cream.
- Adjust Cajun seasoning slowly — some blends are saltier than others. Start with 1 tsp and add more to taste.
- Use high-quality smoked sausage or andouille for the most authentic flavor; read labels to avoid added sugars that increase carbs.
- For a lighter version, swap half the cream for full-fat coconut milk (note: flavor will change slightly).

๐ฅ Why this works for keto
This skillet combines high-fat ingredients (butter, cream, and cheese) with protein (shrimp and sausage) while keeping carbs low — a classic keto approach. Peppers add texture and nutrients without pushing carbs up. The Cajun seasoning delivers deep, layered flavor so the dish feels indulgent even though it’s low-carb. It’s a satisfying, filling meal that supports ketosis without feeling like a bland diet plate.
๐ Flavor Variations & Add-ins
- Garlic butter shrimp: Skip the Cajun spice and add extra garlic, lemon zest, and parsley for a fresher profile.
- Veggie boost: Add sliced mushrooms, zucchini, or a handful of cherry tomatoes for more volume and fiber.
- Cajun chicken: Swap shrimp for diced chicken thighs — brown well and simmer until cooked through.
- Cheesy bake: Transfer to a baking dish, top with extra Parmesan, and broil briefly for a golden crust.
- Dairy-free: Use full-fat coconut cream and nutritional yeast instead of Parmesan (flavor will shift).
๐ง Storage Tips
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently over low heat and add a splash of broth or cream if the sauce has thickened. Freezing is not ideal because cream sauces can separate when thawed, though in a pinch you can freeze and gently re-emulsify while reheating.
❓ Frequently Asked Questions
- Can I use frozen shrimp?
- Yes — thaw completely and pat dry before cooking. Removing surface moisture helps shrimp sear instead of steaming.
- What can I serve this with on keto?
- Zucchini noodles (zoodles), cauliflower rice, sautรฉed greens, or a simple leafy salad are all great low-carb options.
- Is smoked sausage okay on keto?
- Yes, but check the label. Some sausages include sugar or fillers that add carbs — choose a plain smoked sausage or andouille with minimal additives.
- How can I reduce spice for kids?
- Reduce Cajun seasoning to 1 tsp and omit red pepper flakes. Add extra cream to mellow flavors, and finish with a squeeze of lemon for brightness.
- Can I meal prep this?
- Yes — store portions in airtight containers and reheat gently. Add fresh parsley or lemon after reheating for brightness.
