This Creamy Spicy Keto Shrimp and Sausage Skillet is the kind of dinner that feels indulgent but fits perfectly into a low-carb lifestyle. Tender shrimp, smoky sausage, and colorful bell peppers come together in a rich Cajun cream sauce, all ready in just 30 minutes. I make this on nights when I need something satisfying fast, and it never disappoints.

The first time I threw this together on a busy Tuesday night, I honestly could not believe how good it tasted for how little effort it took. The sauce is silky, the shrimp stays juicy, and that smoky heat from the Cajun seasoning builds in the best way. This is the kind of meal that makes your kitchen smell incredible from the moment the sausage hits the pan.

Bold, creamy, and completely weeknight-friendly. Make this tonight!

Ingredients for Creamy Spicy Keto Shrimp and Sausage Skillet

I always keep these ingredients on hand because this skillet comes together with pantry staples and a quick trip to the seafood counter. I recommend using fresh shrimp when you can find it, but a good-quality frozen shrimp works just as well when thawed overnight in the fridge.

For the Protein:

  • 1 lb shrimp, peeled and deveined – I recommend medium to large shrimp for the best texture in every bite
  • 12 oz smoked sausage, sliced into rounds

For the Base:

  • 2 tbsp olive oil
  • 2 tbsp butter – My preference is real unsalted butter for a richer, more balanced sauce
  • 1 medium onion, chopped
  • 1 medium red bell pepper, diced
  • 1 medium green bell pepper, diced

For the Sauce:

  • 2 tbsp Cajun seasoning, divided – In my experience, a low-sodium blend gives you the most control over the final salt level
  • 4 cloves garlic, minced
  • 1 cup chicken broth
  • 1 cup heavy whipping cream
  • 1/2 tsp cayenne pepper (optional, start with less and add more to taste)

To Finish:

  • Salt and pepper to taste
  • Fresh parsley, chopped (optional garnish)

Step-by-Step Instructions

In my experience, the key to this dish is cooking the shrimp and sausage separately first so both develop real color and flavor before the sauce comes together. That sear on the sausage adds a depth you just cannot get any other way.

Step 1: Heat olive oil in a large skillet over medium-high heat until it shimmers, about 2 minutes. Add the shrimp and sliced sausage. Sprinkle with 1 teaspoon of Cajun seasoning and saute for 4 to 5 minutes until the shrimp turns pink and opaque and the sausage picks up a nice golden-brown color. Remove from the skillet and set aside. Do not overcook the shrimp here, as they will go back into the hot sauce later.

Step 2: Reduce the heat to medium. Add butter to the same skillet, then add the chopped onion, red bell pepper, and green bell pepper. Saute for 3 to 4 minutes until the vegetables soften and the onions turn translucent.

Step 3: Stir in the minced garlic and cook for 30 seconds just until fragrant. Watch closely here because garlic burns fast and turns bitter if it sits too long on the heat.

Step 4: Pour in the chicken broth, the remaining Cajun seasoning, heavy whipping cream, and cayenne pepper. Stir to combine and bring to a gentle simmer. Cook for about 5 minutes, stirring occasionally, until the sauce thickens slightly and coats the back of a spoon. If the sauce is still too thin after 5 minutes, simmer for another 2 minutes on low heat before moving on.

Step 5: Return the shrimp and sausage to the skillet and stir gently to coat everything evenly in the creamy Cajun sauce. Season with salt and pepper to taste, garnish with fresh parsley, and serve hot.

Best Sides to Pair with Creamy Spicy Keto Shrimp and Sausage Skillet

This skillet is rich and bold, so the best pairings are simple sides that soak up the sauce without competing with those Cajun flavors.

Cauliflower Rice: The ultimate low-carb base for this dish. It absorbs the creamy Cajun sauce perfectly and keeps the whole meal under 5 grams of net carbs per serving. Try pairing it with this Crispy Oven Roasted Cauliflower if you want to switch things up.

Zucchini Noodles: Light, fresh, and great for adding volume to your plate without extra carbs. The mild flavor lets the smoky, spicy sauce be the star.

Sauteed Asparagus: A slightly bitter, crisp green vegetable balances the richness of the cream sauce and adds a pop of color to the plate. These Healthy Sauteed Vegetables make a great simple side that pairs well here too.

Mixed Green Salad with Vinaigrette: A tangy dressing cuts right through the creaminess and refreshes your palate between bites. This Mediterranean Chickpea Salad with Lemon Vinaigrette is a bright, protein-friendly option that works well alongside this skillet.

Cajun Sausage Pasta: If you are feeding non-keto guests, serve this skillet alongside a bowl of Cajun Sausage Pasta to keep that same bold Southern flavor running through the whole meal.

Creamy Garlic Shrimp: Love shrimp-forward dinners? This Creamy Garlic Shrimp is another quick, low-carb option worth bookmarking for your next weeknight rotation.

How to Store and Reheat This Skillet

Store leftovers in an airtight container in the refrigerator for up to 3 days. Let the skillet cool completely before sealing to prevent condensation from watering down the sauce. For longer storage, freeze in airtight containers for up to 2 months and thaw overnight in the fridge before reheating.

Pro tip: always reheat this Creamy Spicy Keto Shrimp and Sausage Skillet on the stovetop over low heat rather than in the microwave. Stir gently and add a small splash of chicken broth if the sauce has thickened too much overnight. This brings it right back to that silky, creamy consistency without drying out the shrimp.

I recommend prepping ahead if you are planning a busy week. Saute the shrimp, sausage, and vegetables up to 24 hours in advance, store them separately in airtight containers, and then make the sauce fresh when you are ready to serve. The whole dish comes together in under 10 minutes that way.

FAQs

Can I make this dish dairy-free?

Yes. Swap the butter for ghee and replace the heavy whipping cream with full-fat canned coconut milk. The sauce will be slightly different in flavor but will still be rich and creamy.

How do I keep the shrimp from turning rubbery?

Do not overcook them in Step 1. Shrimp only need 4 to 5 minutes total. Once they turn pink and curl into a loose C shape, pull them out of the skillet right away. They will finish warming through when you return them to the sauce.

Can I use chicken instead of shrimp?

Absolutely. Diced boneless chicken breast works great in this recipe. Increase the cook time in Step 1 to about 6 to 8 minutes until the chicken is cooked through to 165 degrees F before setting it aside.

Conclusion

This Creamy Spicy Keto Shrimp and Sausage Skillet is proof that eating low-carb never has to feel like a compromise. It is fast, packed with bold Cajun flavor, and easy enough for any weeknight. Try it once and it will earn a regular spot in your dinner rotation. You are going to love every bite!
