The Method for One-Pot Creamy Cajun Beef Pasta

Step 1: Brown the Ground Beef

Heat 2 tablespoons of olive oil in your large skillet or pot over medium-high heat. Add 1 pound of ground beef, breaking it apart with your spoon. Cook until browned and no longer pink, about 5-7 minutes. Season with a pinch of salt and pepper. Once browned, transfer the beef to a bowl and set aside, leaving the rendered fat in the pot.

Step 2: Sauté Aromatics and Vegetables

In the same pot, add the diced onion and bell pepper. Sauté for about 4-5 minutes until softened. Toss in the minced garlic and cook for an additional minute until fragrant, stirring constantly to prevent burning.

Step 3: Build the Flavor Base

Return the browned beef to the pot. Sprinkle in the 2 tablespoons of Cajun seasoning, stirring well to coat the meat and vegetables evenly. Pour in the entire can of diced tomatoes with their juices and the 2 cups of beef broth. Stir to combine everything.

Step 4: Add Pasta and Simmer

Add the 8 ounces of penne pasta directly into the pot. Give it a good stir to submerge the pasta in the liquid. Bring the mixture to a boil, then reduce to a simmer. Cover with a lid and let cook for about 12 minutes, stirring occasionally to prevent sticking, until the pasta is tender and has absorbed most of the liquid.

Step 5: Finish with Cream and Cheese

Once the pasta is cooked, stir in 1 cup of heavy cream. Let it simmer uncovered for 2-3 minutes until the sauce thickens slightly. Remove from heat and mix in the 1/2 cup of grated Parmesan cheese until melted and creamy. Adjust seasoning with additional salt and pepper if needed.

Step 6: Garnish and Serve

Sprinkle chopped fresh parsley over the pasta for a pop of color and freshness. Serve immediately, and enjoy the rich, spicy, and creamy goodness of your One-Pot Creamy Cajun Beef Pasta.

Smart Substitutions

Pasta: Swap penne with rigatoni, fusilli, or even gluten-free pasta to suit your preference.
Ground Beef: Use ground turkey or chicken for a leaner option without compromising flavor.
Heavy Cream: Substitute with coconut cream or cashew cream for a dairy-free creamy texture.
Beef Broth: Vegetable broth works well if you’re looking for a lighter or meat-free alternative.
Cajun Seasoning: Adjust the amount or make your own blend with paprika, garlic powder, cayenne, and oregano for customized heat.

Problems & Prevention

Pasta sticking together: Stir frequently during simmering and make sure the pasta is submerged in liquid.
Overcooked pasta: Keep an eye on the cooking time and test the pasta early to avoid mushiness.
Burning the garlic: Add garlic after the onions and peppers have softened to prevent it from turning bitter.
Sauce too thin: Let it simmer uncovered after adding cream to reduce and thicken the sauce.
Too spicy: Reduce Cajun seasoning or balance heat with extra cream or cheese.

Save It for Later

This dish stores beautifully in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of broth or cream to restore the creamy texture. For meal prep, portion into individual containers for easy grab-and-go lunches or dinners.
