  • 1 medium onion, finely chopped

  • 3 cloves garlic, minced
  • 1 green bell pepper, diced

For the Creamy Parmesan Sauce:

  • 2 tbsp butter
  • 2 tbsp all-purpose flour
  • 1 cup (240 ml) chicken or beef broth
  • 2 cups (480 ml) whole milk (or half-and-half for richness)
  • 1 cup (100 g) freshly grated Parmesan cheese
  • ½ cup (120 ml) heavy cream
  • Pinch of red pepper flakes (optional, for heat)

Optional Garnishes:

  • Fresh parsley or green onions, chopped
  • Extra Parmesan for serving
  • Lemon wedges for brightness

Equipment Needed

  • Large pot for pasta
  • Large skillet or Dutch oven
  • Wooden spoon or spatula
  • Whisk for sauce
  • Strainer or colander

Step-by-Step Instructions

Step 1: Cook the Pasta

  • Bring a large pot of salted water to a boil.
  • Cook spaghetti until al dente, according to package directions.
  • Reserve ½ cup of pasta water, then drain and set aside.

Step 2: Cook the Beef and Veggies

  • Heat olive oil in a skillet or Dutch oven over medium-high heat.
  • Add ground beef, breaking it apart with a spoon, and cook until browned (5–6 minutes).
  • Add onion and bell peppers. Sauté until softened, about 4 minutes.
  • Stir in garlic, Cajun seasoning, smoked paprika, salt, and pepper. Cook for 1–2 minutes more.

Step 3: Make the Parmesan Cream Sauce

  • In the same pan (push beef mixture to the side if needed), melt butter over medium heat.
  • Whisk in flour and cook for 1 minute to form a roux.
  • Slowly whisk in milk and broth until smooth.
  • Bring to a gentle simmer and stir until thickened, about 5 minutes.
  • Stir in Parmesan cheese and heavy cream. Let melt into a silky sauce.

Step 4: Combine Pasta and Sauce

  • Add drained spaghetti to the skillet with beef and sauce.
  • Toss well until pasta is coated. If the sauce seems too thick, add a splash of reserved pasta water.
  • Taste and adjust seasoning.

Step 5: Garnish and Serve

  • Sprinkle with fresh parsley or green onions.
  • Add extra Parmesan or red pepper flakes for a finishing touch.
  • Serve hot with garlic bread or a fresh salad.

Expert Tips for Success

  • Homemade Cajun Seasoning: Mix paprika, garlic powder, onion powder, oregano, thyme, cayenne, salt, and pepper for full control over spice.
  • Cheese quality matters: Always grate Parmesan from a block—it melts smoother and tastes richer.
  • Balance the spice: Add cream or milk if the Cajun seasoning makes it too spicy.
  • Sauce consistency: If sauce is too thin, simmer longer; if too thick, add more broth or pasta water.
  • One-pot option: Cook spaghetti directly in the sauce and broth mixture for deeper flavor.

Flavor Variations

  • Veggie Boost: Add mushrooms, zucchini, or spinach for extra nutrition.
  • Protein Swap: Use ground turkey, chicken, or sausage instead of beef.
  • Seafood Twist: Shrimp or crawfish make a fun Cajun-inspired variation.
  • Cheesy Upgrade: Stir in mozzarella or pepper jack for extra gooeyness.
  • Lighter Version: Use light cream or evaporated milk instead of heavy cream.

Serving Suggestions

Pair your Cajun Beef Spaghetti with:

  • Warm garlic bread or cheesy breadsticks
  • A crisp Caesar or garden salad
  • Roasted vegetables like broccoli, zucchini, or asparagus
  • A glass of iced tea or sparkling water with lemon for balance

Storage & Reheating

  • Refrigeration: Store leftovers in an airtight container for up to 3 days.
  • Freezing: Freeze cooled pasta in a freezer-safe container for up to 2 months. Thaw overnight before reheating.
  • Reheating: Warm in a skillet with a splash of milk or broth to revive the creamy sauce.
