Ingredients
Method
- Prep the base: Add sliced onions, bell peppers, and garlic to the crockpot. Drizzle with oil and toss with Cajun seasoning, smoked paprika, and thyme.
- Add sausage and broth: Layer the andouille on top of the veggies. Pour in the chicken broth. This gives moisture and lets the spices bloom during the cook.
- Slow cook: Cover and cook on Low for 4–5 hours or High for 2–2.5 hours, until the peppers are tender and the sausage is juicy.
- Make it creamy: Stir in the heavy cream and cream cheese. Cover and cook on High for 15–20 minutes, then whisk or stir until the sauce is smooth. Taste and adjust salt and pepper.
- Add shrimp: Nestle the shrimp into the sauce. Cover and cook on High for 10–15 minutes, just until the shrimp turn pink and opaque. Do not overcook.
- Finish and serve: Garnish with chopped parsley or green onions. Serve as-is or spoon over riced cauliflower for a complete keto plate.
Why This Recipe Works
This dish layers flavor in a smart way: andouille sausage brings smoky heat, while Cajun seasoning adds a balanced kick. Slow cooking allows the onions and peppers to soften and sweeten, rounding out the spice.
Stirring in cream and a touch of cream cheese at the end creates a silky sauce without flour or thickeners. Shrimp cook quickly in the final minutes, so they stay plump and tender, never rubbery. Best of all, it’s low-carb, naturally gluten-free, and easy to customize.

Step-by-Step Instructions

How to Store
Let leftovers cool, then store in an airtight container in the fridge for up to 3 days. Reheat gently on the stove over low heat or in the microwave at 50–60% power.
If the sauce tightens, add a splash of broth or cream to loosen. For best texture, avoid freezing due to the cream and shrimp, which can become grainy and rubbery after thawing.
Health Benefits
- Keto-friendly macros: High in protein and fat with minimal carbs from peppers and onions, making it satisfying without spiking blood sugar.
- Nutrient-dense seafood: Shrimp provides lean protein, selenium, iodine, and B12 for metabolic and thyroid support.
- Anti-inflammatory spices: Paprika, garlic, and thyme offer antioxidants that support immune and heart health.
- Healthy fats: Cream and olive oil increase satiety and help absorb fat-soluble vitamins from the veggies.
Common Mistakes to Avoid
- Overcooking the shrimp: Add them at the end and pull as soon as they’re pink and firm. Overcooked shrimp turn rubbery fast.
- Using too salty seasoning: If your Cajun blend contains salt, reduce added salt and use low-sodium broth to avoid an overly salty dish.
- Skipping the cream cheese: It stabilizes and thickens the sauce.
If you omit it, the sauce may separate or feel thin.
- Not softening cream cheese: Cold chunks won’t melt smoothly. Cube it and let it sit at room temp while the crockpot runs.
- Not enough liquid: Crockpots vary. If your unit runs hot, check at the halfway mark and add 1/4 cup broth if things look dry.
Variations You Can Try
- Extra heat: Add 1/4–1/2 teaspoon cayenne or a few dashes of hot sauce with the cream for spicier kick.
- Different sausage: Use smoked kielbasa or chorizo if you can’t find andouille.
Choose a low-carb option.
- Veggie swap: Add sliced celery or a handful of spinach in the last 10 minutes for more greens without extra carbs.
- Tomato twist: Stir in 1/2 cup drained diced tomatoes before slow cooking for a Creole-style vibe. Keep an eye on carbs.
- Dairy-light: Replace some cream with unsweetened coconut milk and use less cream cheese for a lighter sauce.
- Skillet finish: For a thicker, clingy sauce, transfer cooked mixture to a skillet at the end and simmer 3–5 minutes to reduce.
FAQ
Can I use frozen shrimp?
Yes, but thaw them first and pat dry so they don’t water down the sauce. Add thawed shrimp in the final 10–15 minutes on High.
How spicy is this dish?
It’s medium by default.
Choose a mild Cajun blend for less heat, or add cayenne and hot sauce for more fire.
What can I serve this with on keto?
Riced cauliflower is the go-to. You can also serve it with sautéed zucchini, spaghetti squash, or a simple side salad with olive oil.
Can I cook it on the stovetop instead?
Yes. Sauté sausage, onions, and peppers in a large skillet, add spices and broth, simmer 10–15 minutes, then stir in cream and cream cheese.
Add shrimp and cook just until pink.
How do I prevent a curdled sauce?
Stir in cream and cream cheese after the slow cook, on High but not boiling. Whisk until smooth, then add the shrimp. Avoid prolonged high heat once dairy is added.
Is there a dairy-free version?
Use full-fat coconut milk and a dairy-free cream cheese alternative.
The flavor changes slightly but stays rich and satisfying.
Can I make it ahead?
You can prep the veggies and sausage in the crock the night before. In the morning, add broth and start cooking. Add dairy and shrimp just before serving.
What if I don’t have Cajun seasoning?
Mix paprika, garlic powder, onion powder, dried thyme, dried oregano, black pepper, and a pinch of cayenne.
Add salt to taste if your blend is salt-free.
