Ingredients Method

Ingredients

  

• 1 pound large shrimp, peeled and deveined (tails on or off)
• 12 ounces smoked andouille or kielbasa sausage, sliced into 1/2-inch rounds
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 small red onion, sliced
• 2 cups zucchini, chopped into half-moons
• 2 tablespoons avocado oil or olive oil, divided
• 2 teaspoons Cajun seasoning (more to taste)
• 1/2 teaspoon smoked paprika (optional for extra smokiness)
• 1/2 teaspoon garlic powder
• 1/4 teaspoon cayenne pepper (optional for heat)
• 1 teaspoon kosher salt, divided (adjust to taste)
• 1/2 teaspoon black pepper
• 2 cloves garlic, minced
• 1 tablespoon lemon juice, plus wedges for serving
• 2 tablespoons chopped fresh parsley
• Optional sides for serving: cauliflower rice, sautéed greens, or shirataki rice

Method

 

1. Prep the shrimp: Pat shrimp dry with paper towels. Toss with 1 teaspoon Cajun seasoning, 1/4 teaspoon salt, and a drizzle of oil. Set aside.
2. Season the veggies: In a bowl, mix bell peppers, onion, and zucchini with 1 tablespoon oil, 1 teaspoon Cajun seasoning, smoked paprika, garlic powder, 1/2 teaspoon salt, and black pepper.
3. Brown the sausage: Heat a large skillet over medium-high. Add sliced sausage and cook 3–4 minutes, stirring, until edges are browned. Remove to a plate.
4. Sauté the veggies: In the same skillet, add remaining oil. Add the seasoned veggies and cook 5–7 minutes, stirring occasionally, until crisp-tender with light char.
5. Add garlic: Stir in minced garlic during the last minute of cooking so it becomes fragrant without burning.
6. Cook the shrimp: Push veggies to the sides. Add shrimp to the center in a single layer. Cook 1–2 minutes per side until pink and opaque.
7. Combine and finish: Return sausage to the skillet. Squeeze in lemon juice and toss everything to coat. Taste and adjust seasoning, adding more Cajun spice or salt if needed.
8. Garnish: Remove from heat and sprinkle with chopped parsley. Add lemon wedges on the side if you like extra brightness.
9. Portion for meal prep: Divide into 4 meal prep containers. Add optional cauliflower rice or greens to keep it low-carb.

Storage Instructions

• Refrigerator: Store in airtight containers for up to 4 days.
• Freezer: Shrimp can get rubbery after freezing, but it works in a pinch. Cool fully, then freeze up to 2 months. Thaw overnight in the fridge and reheat gently.
• Reheating: Microwave 60–90 seconds, stirring halfway.

  Or reheat in a skillet over medium heat with a splash of water or oil for 3–4 minutes.

• Meal prep tip: If using cauliflower rice, store it separately and reheat it first to keep the shrimp from overcooking.

Why This is Good for You

• Low-carb and high-protein: Shrimp and sausage deliver protein without the blood sugar spike.
• Healthy fats: Sausage and cooking oil keep you fuller longer and support ketosis.
• Micronutrient boost: Bell peppers, onion, and zucchini add fiber, potassium, vitamin C, and antioxidants.
• No added sugar or grains: Clean keto profile that fits most low-carb plans.

Common Mistakes to Avoid

• Overcooking shrimp: They only need 1–2 minutes per side. Pull them as soon as they turn pink and opaque.
• Skipping the dry pat: Pat shrimp and veggies dry. Too much surface moisture leads to steaming instead of searing.
• Crowding the pan: Use a large skillet.

  If needed, cook in batches to get that nice char.

• Under-seasoning: Cajun blends vary. Taste and adjust at the end with more seasoning, salt, or lemon.
• Using sweet sausage: Choose smoked andouille or a sugar-free kielbasa to keep it keto and spicy.

Recipe Variations

• Extra smoky: Add more smoked paprika or a splash of liquid smoke.
• Creamy Cajun: Stir in 2–3 tablespoons heavy cream or coconut cream at the end for a silky finish.
• Veggie swap: Use broccoli florets, asparagus, or green beans if that’s what you have.
• Heat control: Use mild sausage and skip cayenne for a gentle version. Add crushed red pepper for more kick.
• Surf-and-turf: Replace half the shrimp with diced chicken thighs.

  Brown chicken first, then proceed.

• Lemon herb twist: Finish with lemon zest and extra parsley or thyme for a brighter profile.
• Meal prep bowls: Serve over cauliflower rice with a dollop of garlic aioli or a drizzle of olive oil.

FAQ

Is this recipe spicy?

It has a gentle heat if you follow the base measurements. Use less Cajun seasoning or skip the cayenne for mild, or add more for a fiery bowl.

What Cajun seasoning should I use?

Choose a blend without added sugar or unnecessary fillers. Look for paprika, garlic, onion, black pepper, and cayenne as the main ingredients.

Adjust salt since some blends are salty.

Can I use frozen shrimp?

Yes. Thaw overnight in the fridge or run under cold water until thawed. Pat very dry before cooking to avoid excess moisture.

What if I don’t have andouille?

Kielbasa or another smoked, fully cooked sausage works.

Check the label for hidden sugars to keep it keto-friendly.

How do I keep the veggies from getting soggy?

Use high heat, don’t overcrowd the pan, and keep the pieces similar in size. Stir occasionally, not constantly, to encourage browning.

Can I make it dairy-free?

Absolutely. The base recipe is dairy-free.

If you try the creamy variation, use coconut cream instead of heavy cream.

How many servings does this make?

It makes about 4 meal prep portions. Pair with a low-carb side if you want larger meals.

What sides go well with this?

Cauliflower rice, sautéed spinach, roasted broccoli, or simple mixed greens with olive oil and lemon are great low-carb choices.

How can I add more fat for keto macros?

Finish with a drizzle of olive oil, serve with avocado slices, or stir in a tablespoon of butter or ghee at the end.

Can I grill instead of using a skillet?

Yes. Skewer shrimp and sausage, toss veggies in oil and seasoning, and grill over medium-high heat.

Combine and finish with lemon and parsley before serving.
