Ingredients Method

Ingredients

  

• 1 pound large shrimp, peeled and deveined (tails on or off)
• 12 ounces smoked sausage or andouille, sliced into 1/2-inch rounds
• 1 small onion, finely chopped
• 4 cloves garlic, minced
• 1 red bell pepper, thinly sliced (optional, for color and sweetness)
• 1 cup heavy cream
• 4 ounces cream cheese, cut into cubes
• 1/2 cup chicken broth (low-sodium)
• 1/2 cup grated Parmesan cheese
• 2 tablespoons unsalted butter
• 1 teaspoon smoked paprika
• 1/2 teaspoon crushed red pepper flakes (optional, to taste)
• 1/2 teaspoon dried thyme or Italian seasoning
• Salt and black pepper, to taste
• 2 tablespoons chopped fresh parsley (for garnish)
• Lemon wedges, for serving

Method

 

1. Brown the sausage (optional but recommended): In a skillet over medium heat, sear the sliced sausage in butter for 3–4 minutes to develop color. Transfer to the slow cooker.
2. Build the base: Add onion, garlic, and bell pepper to the slow cooker. Sprinkle in smoked paprika, red pepper flakes, and thyme. Pour in chicken broth.
3. Add the creamy elements: Scatter the cream cheese cubes over the top. Pour in the heavy cream and add Parmesan. Give it a gentle stir—no need to fully combine yet.
4. Cook low and slow: Cover and cook on Low for 2–2.5 hours, or on High for 1–1.5 hours, until the sauce is smooth and the onions are tender.
5. Add the shrimp: Stir the sauce well, then add the shrimp. Season with salt and pepper. Cook on Low for 20–30 minutes (or High for 10–15 minutes) until shrimp are pink and just cooked through.
6. Finish and taste: Stir in parsley. Adjust salt, pepper, and heat (more red pepper flakes if you like). The sauce should be glossy and lightly thickened.
7. Serve: Spoon over zucchini noodles, spaghetti squash, riced cauliflower, or sautéed greens. Add a squeeze of lemon right before serving.

1. Brown the sausage (optional but recommended): In a skillet over medium heat, sear the sliced sausage in butter for 3–4 minutes to develop color. Transfer to the slow cooker.
2. Build the base: Add onion, garlic, and bell pepper to the slow cooker.

   Sprinkle in smoked paprika, red pepper flakes, and thyme. Pour in chicken broth.

3. Add the creamy elements: Scatter the cream cheese cubes over the top. Pour in the heavy cream and add Parmesan.

   Give it a gentle stir—no need to fully combine yet.

5. Add the shrimp: Stir the sauce well, then add the shrimp. Season with salt and pepper. Cook on Low for 20–30 minutes (or High for 10–15 minutes) until shrimp are pink and just cooked through.

7. Serve: Spoon over zucchini noodles, spaghetti squash, riced cauliflower, or sautéed greens. Add a squeeze of lemon right before serving.

Keeping It Fresh

• Storage: Cool completely, then store in an airtight container in the fridge for up to 3 days.
• Reheating: Warm gently over low heat on the stovetop or in the microwave at 50% power.

  Add a splash of cream or broth to loosen the sauce.

• Freezing: Not ideal due to dairy and shrimp texture. If you must, freeze the sauce without shrimp; add freshly cooked shrimp after reheating.
• Make-ahead tip: Prep sausage, onions, peppers, and seasonings in a bag the night before. In the morning, add to the crockpot with liquids and cream cheese; add shrimp later.

Health Benefits

• Low-carb and keto-friendly: Keeps net carbs low while delivering satisfying fat and protein.
• Protein-packed: Shrimp and sausage provide complete proteins to support satiety and muscle maintenance.
• Micronutrients: Shrimp brings selenium, iodine, and B12; bell peppers add vitamin C; dairy contributes calcium.
• Customizable fats: You control the fat sources and can choose clean-label sausages and quality dairy.

Pitfalls to Watch Out For

• Overcooking shrimp: Add shrimp at the end and watch closely.

  They go from perfect to rubbery fast.

• Curdled sauce: Keep heat moderate and avoid extended High settings after dairy is added. Stir gently once or twice.
• Hidden carbs in sausage: Read labels. Skip sausages with added sugars, fillers, or breadcrumbs.
• Too salty: Use low-sodium broth and season at the end, especially if your sausage is already salty.
• Watery sauce: If it’s thin, remove the lid for the last 15 minutes on High, or whisk in extra Parmesan to thicken.

Alternatives

• Protein swaps: Try chicken thighs or turkey sausage.

  For pescatarian vibes, use all shrimp or add scallops near the end.

• Dairy-free: Use full-fat coconut milk and a dairy-free cream cheese alternative. Replace Parmesan with nutritional yeast to taste.
• Veggie add-ins: Mushrooms, spinach, zucchini, or broccoli florets (add in the last hour so they don’t overcook).
• Flavor twists: Cajun seasoning instead of paprika and thyme; a splash of dry white wine (reduce broth slightly); or fresh basil instead of parsley.
• Heat level: Swap red pepper flakes for diced jalapeño or a pinch of cayenne. Keep it mild by skipping heat entirely.

FAQ

Can I cook this on the stovetop instead of a slow cooker?

Yes.

Brown the sausage, sauté onions and peppers, add garlic, then stir in broth, cream, cream cheese, and Parmesan. Simmer gently until smooth, then add shrimp and cook 3–5 minutes until pink.

What size shrimp should I use?

Large or extra-large (16/20 to 21/25 count) work best. They stay juicy and don’t overcook as quickly in the crockpot.

How do I thicken the sauce without flour or cornstarch?

Rely on cream cheese and Parmesan.

If it still needs body, simmer uncovered briefly or add a bit more Parmesan.

Is andouille too spicy for this?

It depends on the brand. If you’re heat-sensitive, use smoked sausage or kielbasa and add red pepper flakes to taste so you control the spice.

What can I serve it with that’s still keto?

Zucchini noodles, riced cauliflower, spaghetti squash, sautéed kale, or roasted asparagus all pair nicely.

Can I use frozen shrimp?

Yes, but thaw and pat dry first to avoid watering down the sauce. Add them at the end as directed.

How do I avoid a greasy sauce?

Use quality sausage and drain excess fat if it renders heavily.

Balance with a touch more broth or a squeeze of lemon to brighten.

Can I double the recipe?

Yes, as long as your slow cooker has room. Add 15–30 minutes to the initial cook time before adding shrimp, and watch texture.
