Why You’ll Love This Creamy Cajun Garlic Butter Spaghetti with Beef Strips

This dish is the perfect mix of spicy and savory, creamy and bold. The Cajun seasoning delivers that punchy warmth, while garlic butter brings in the familiar cozy notes. Using spaghetti makes it satisfying and accessible, but the beef strips elevate it into something memorable. If you love meals that come together quickly yet taste like they took hours, this one is for you.

What Kind of Beef Strips Should I Use?

Flank steak or sirloin are both great choices because they cook quickly and stay tender when sliced against the grain. Look for cuts with a little marbling for added flavor. Avoid overcooking—a quick sear is all they need before finishing in the sauce. If you’re short on time, pre-cut beef strips from the butcher section also work beautifully.

Ingredients for the Creamy Cajun Garlic Butter Spaghetti with Beef Strips

Every element in this dish is chosen for both flavor and texture, resulting in a pasta experience that hits all the right notes. The ingredients are straightforward and pantry-friendly, with a few flavor boosters that make all the difference.

• Spaghetti: Classic and easy to find, spaghetti gives a great texture to soak up the creamy Cajun sauce.
• Beef strips: Choose tender cuts like sirloin or flank steak. They cook quickly and hold flavor exceptionally well.
• Butter: This creates the luscious base for our sauce and brings that melt-in-your-mouth richness.
• Garlic: Fresh garlic is essential for that deep, aromatic flavor that defines this dish.
• Heavy cream: It adds creaminess and balances out the spice from the Cajun seasoning.
• Cajun seasoning: This is the heart of the dish—a blend of paprika, cayenne, garlic powder, and herbs that give it warmth and kick.
• Parmesan cheese: Adds salty umami richness to the sauce and helps it thicken beautifully.
• Salt and pepper: Essential for bringing out all the flavors.
• Olive oil: Used to sear the beef and lightly toast the garlic before building the sauce.

How To Make the Creamy Cajun Garlic Butter Spaghetti with Beef Strips

Step 1: Sear the Beef

Heat olive oil in a large skillet over medium-high heat. Season the beef strips with salt, pepper, and a light sprinkle of Cajun seasoning. Sear until browned on both sides, about 2 minutes per side. Remove from the pan and set aside.

Step 2: Cook the Pasta

Boil spaghetti in salted water according to package instructions until al dente. Drain and reserve about a cup of the pasta water.

Step 3: Build the Sauce Base

In the same skillet, melt butter and add minced garlic. Sauté until fragrant, then add more Cajun seasoning. Pour in the heavy cream and bring to a simmer.

Step 4: Add Cheese and Combine

Stir in the Parmesan cheese until melted. Add the cooked spaghetti to the sauce and toss gently to coat. Use a bit of reserved pasta water if needed to loosen the sauce.

Step 5: Finish with the Beef

Return the beef strips to the skillet and let them warm through in the sauce. Taste and adjust seasoning if needed.

Serve immediately, garnished with extra Parmesan or chopped parsley if desired.

How to Serve and Store Creamy Cajun Garlic Butter Spaghetti with Beef Strips

This pasta is best served hot, right after tossing everything together so the sauce is still silky and clinging to the noodles. It comfortably serves four people as a main course and will leave everyone reaching for seconds.

If you have leftovers, store them in an airtight container in the fridge for up to 3 days. When reheating, add a splash of milk or water to help bring the sauce back to life. Gently warm it over low heat on the stove or microwave in intervals, stirring in between.
