Ingredients for Creamy Garlic Butter Steak & Cajun Shrimp with Peppers

This recipe makes approximately four servings.

For the Steak

• 1 pound sirloin steak, ribeye, or New York strip
• 1 tablespoon olive oil
• 2 tablespoons unsalted butter
• 1 teaspoon garlic powder
• ½ teaspoon smoked paprika
• ½ teaspoon onion powder
• ½ teaspoon salt, or to taste
• ¼ teaspoon freshly ground black pepper

For the Cajun Shrimp

• 1 pound large shrimp, peeled and deveined
• 1 tablespoon olive oil
• 1 teaspoon Cajun seasoning
• ½ teaspoon paprika
• 2 cloves garlic, minced
• 1 tablespoon fresh lemon juice
• 1 tablespoon butter

For the Peppers and Onions

• 1 red bell pepper, thinly sliced
• 1 yellow or orange bell pepper, thinly sliced
• ½ medium onion, thinly sliced
• 1 tablespoon olive oil
• ½ teaspoon Italian seasoning
• ¼ teaspoon black pepper

For the Creamy Garlic Butter Sauce

• 3 tablespoons unsalted butter
• 4 cloves garlic, minced
• 1 cup heavy cream
• ½ cup freshly grated Parmesan cheese
• ½ teaspoon Cajun seasoning
• ¼ teaspoon smoked paprika
• ¼ teaspoon black pepper
• 1 teaspoon lemon juice, optional

Ingredient tip: Use freshly grated Parmesan rather than pre-shredded cheese when possible. It generally melts more smoothly into cream sauce. For the best flavor, choose steak with good marbling and large shrimp that are similar in size.

How to Make Creamy Garlic Butter Steak & Cajun Shrimp with Peppers

Step 1: Prepare and Season the Steak

Pat the steak dry with paper towels. This helps remove surface moisture so the meat can develop a flavorful crust.

Cut the steak into approximately 1-inch cubes. In a bowl, toss the steak with garlic powder, smoked paprika, onion powder, salt, and black pepper.

Let the seasoned steak sit while you prepare the shrimp and vegetables.

If your steak is particularly thick or uneven, cut the pieces as uniformly as possible so they cook at a similar rate.

Step 2: Season the Cajun Shrimp

Pat the peeled and deveined shrimp dry.

Place them in a bowl and add the Cajun seasoning, paprika, minced garlic, and lemon juice. Toss gently until the shrimp are evenly coated.

If your Cajun seasoning contains salt, taste the finished dish before adding additional salt.

Set the shrimp aside in the refrigerator while you cook the steak and vegetables. Avoid leaving raw seafood at room temperature for extended periods.

Step 3: Sear the Steak

Heat a large skillet over medium-high heat. Add the olive oil and allow it to become hot.

Arrange the steak pieces in a single layer, leaving a little space between them. Cook in batches if necessary to avoid overcrowding the pan.

Sear for approximately 2–3 minutes per side, depending on the size of the cubes and your preferred doneness.

During the final minute, add 2 tablespoons of butter and swirl it around the pan. Spoon the melted butter over the steak to add flavor.

Transfer the steak to a clean plate and let it rest. Avoid washing the skillet because the browned bits left behind will add flavor to the sauce.

Important: Cooking time alone cannot guarantee a particular doneness or safe internal temperature. Check the steak with a food thermometer, especially if serving anyone at increased risk from foodborne illness.

Step 4: Cook the Bell Peppers and Onions

Reduce the heat to medium and add 1 tablespoon of olive oil to the same skillet.

Add the sliced red bell pepper, yellow or orange bell pepper, and onion.

Cook for approximately 4–6 minutes, stirring occasionally, until the vegetables begin to soften and develop lightly browned edges.

Sprinkle in the Italian seasoning and black pepper. Stir to distribute the seasonings evenly.

For softer vegetables, cook for another 2–3 minutes. If you prefer a little crunch, remove them from the pan while they still retain their texture.

Transfer the vegetables to a plate.

Step 5: Cook the Cajun Shrimp

Add 1 tablespoon of butter to the skillet and allow it to melt.

Arrange the seasoned shrimp in a single layer. Cook for approximately 1–2 minutes per side, depending on their size.

The shrimp should turn pink and opaque. For food safety, cook them until the thickest part reaches 145°F (63°C).

Avoid overcooking, as shrimp can quickly become tough and rubbery.

Transfer the cooked shrimp to a clean plate.

Step 6: Make the Creamy Garlic Butter Sauce

Reduce the heat to medium-low. Add the remaining 3 tablespoons of butter to the skillet.

Once melted, add the minced garlic and cook for approximately 30–60 seconds, stirring frequently until fragrant.

Do not let the garlic become dark brown, as burnt garlic can make the sauce bitter.

Pour in the heavy cream and stir, scraping up any flavorful browned bits from the bottom of the skillet.

Add the Cajun seasoning, smoked paprika, and black pepper. Bring the mixture to a gentle simmer and cook for approximately 2–3 minutes.

Gradually stir in the Parmesan cheese until it melts into the cream. Continue cooking gently until the sauce thickens enough to coat the back of a spoon.

Avoid boiling the sauce vigorously, as excessive heat can cause it to separate.

If the sauce becomes too thick, add a tablespoon or two of water or unsalted broth until it reaches your preferred consistency.

Step 7: Combine Everything

Return the cooked steak, Cajun shrimp, bell peppers, and onions to the skillet.

Gently toss everything in the creamy garlic butter sauce until evenly coated.

Allow the ingredients to warm together for approximately 1–2 minutes. Do not leave the skillet over the heat longer than necessary, as the steak and shrimp can become overcooked.

Add the optional teaspoon of lemon juice to brighten the flavor.

Taste the sauce and adjust the seasoning if needed.

Step 8: Garnish and Serve

Remove the skillet from the heat and sprinkle the dish with chopped fresh parsley.

Serve immediately while the sauce is warm and creamy.

For an attractive presentation, arrange the steak and shrimp on a large serving platter, spoon the sauce over the top, and finish with extra parsley and a small squeeze of fresh lemon juice.

Tips for the Best Steak and Cajun Shrimp

Choose a suitable steak cut. Sirloin is a good balance of flavor and value, while ribeye provides extra richness because of its marbling.

Dry the steak before searing. Surface moisture prevents proper browning, so use paper towels before seasoning.

Avoid overcrowding the pan. Too many steak pieces at once can cause them to steam rather than sear. Cook in batches when necessary.

Cook the shrimp separately. Shrimp cook much faster than steak, so adding them at the right time helps prevent a rubbery texture.

Adjust the Cajun seasoning. Some blends are much saltier and spicier than others. Start with the recommended amount and add more gradually.

Use freshly grated Parmesan. It usually melts more smoothly into the sauce than some pre-shredded varieties.

Keep the sauce at a gentle simmer. High heat can cause cream sauces to separate or become grainy.

Finish with lemon. A small amount of lemon juice cuts through the richness of the butter and cream without overpowering the dish.

Delicious Variations to Try

1. Spicy Cajun Steak and Shrimp

For a hotter version, add ¼ teaspoon of cayenne pepper or a pinch of red pepper flakes to the Cajun seasoning.

Taste as you go because some Cajun seasoning blends already contain considerable heat.

2. Garlic Parmesan Steak and Shrimp

Increase the Parmesan to ¾ cup and add an extra clove of garlic to the sauce.

This variation has a richer, more pronounced cheese flavor and pairs especially well with fettuccine or mashed potatoes.

3. Steak and Shrimp with Mushrooms

Add 8 ounces of sliced mushrooms to the skillet after cooking the peppers.

Cook until the mushrooms release their moisture and begin to brown, then prepare the cream sauce as directed.

Mushrooms add an earthy flavor that complements the steak and garlic butter beautifully.

4. Creamy Cajun Steak and Shrimp Pasta

Prepare the recipe as written and serve it over cooked fettuccine, linguine, or penne.

Reserve a little pasta water and add it to the sauce if necessary to help the creamy mixture coat the pasta evenly.

5. Low-Carbohydrate Steak and Shrimp Bowl

Serve the steak, shrimp, peppers, and sauce over cauliflower rice or alongside roasted broccoli.

The basic ingredients are naturally low in carbohydrates, although the exact nutritional content depends on the portions and products used.

6. Steak and Shrimp with Spinach

Stir two handfuls of fresh spinach into the sauce before returning the steak and shrimp to the skillet.

Cook just until the spinach wilts, then add the remaining ingredients and serve.

What to Serve with Creamy Garlic Butter Steak and Shrimp

This hearty surf-and-turf recipe pairs well with sides that absorb the sauce or provide a fresh contrast.

• Garlic mashed potatoes: Their creamy texture complements the rich Parmesan sauce.
• Steamed white rice: A simple base that soaks up the garlic butter sauce.
• Fettuccine pasta: Turns the recipe into a satisfying steak and shrimp pasta dinner.
• Roasted asparagus: Adds a fresh, slightly earthy flavor.
• Garlic green beans: Provide a crisp vegetable side.
• Roasted broccoli: Adds color and balances the richness of the cream.
• Buttered corn: Its natural sweetness complements the Cajun spices.
• Crusty bread: Perfect for soaking up the remaining sauce.

For a special dinner, serve the steak and shrimp over mashed potatoes with roasted asparagus on the side.

How to Store Leftovers

Allow leftovers to cool slightly and transfer them to an airtight container within two hours of cooking.

Refrigerate at 40°F (4°C) or below and consume within 3–4 days.

For the best texture, reheat leftovers gently in a skillet over low heat. Add a small splash of cream, milk, or broth to loosen the sauce, stirring until everything is heated through.

Avoid boiling the sauce during reheating, as high heat may cause it to separate. Heat the steak and shrimp only as long as necessary to prevent them from becoming tough.

You can also reheat individual portions in the microwave using short intervals, stirring carefully between intervals.

Can You Freeze Creamy Garlic Butter Steak and Shrimp?

Freezing is possible, but it is not the best option for this recipe. Cream-based sauces can separate after thawing, while cooked shrimp and steak may become tougher.

For the best flavor and texture, refrigerate leftovers and enjoy them within the recommended storage period.

Frequently Asked Questions

What steak is best for creamy garlic butter steak and shrimp?

Sirloin is an excellent everyday option because it is flavorful and relatively easy to cut into cubes. Ribeye offers a richer flavor and more marbling, while New York strip provides a balance of tenderness and beefy taste.

Can I use frozen shrimp?

Yes. Thaw the shrimp completely in the refrigerator or under cold running water, then pat them dry before seasoning. This helps them cook evenly and prevents excess moisture from diluting the sauce.

How do I keep the steak tender?

Choose a suitable cut, avoid overcrowding the pan, and do not overcook the steak. Cut against the grain when appropriate and allow larger pieces to rest briefly before serving.

You can substitute half-and-half, but the sauce will be thinner and may be more sensitive to high heat. For the best consistency, use heavy cream and allow the sauce to simmer gently.

Is Cajun seasoning very spicy?

Cajun seasoning varies by brand. Some blends are mild and smoky, while others contain more cayenne pepper. Start with the recommended quantity and adjust according to your taste.

Can I prepare this recipe ahead of time?

You can slice the vegetables, measure the seasonings, and prepare the garlic ahead of time. For the best texture, cook the steak and shrimp shortly before serving and prepare the cream sauce fresh.
