Key Ingredients & Substitutions
Spaghetti: Regular spaghetti works great, but you can switch it up with whole wheat or gluten-free pasta for different textures. I’ve tried penne, too, and it holds sauce well!
Ground Beef: You can use ground turkey or chicken if you’re looking for a lighter option. Just note that they may need a little extra seasoning due to their milder flavor.
Cajun Seasoning: Feel free to use store-bought Cajun seasoning or make your own with paprika, cayenne, garlic powder, and herbs. If you want it milder, reduce the cayenne or use mild paprika.
Tomato Sauce: If you don’t have tomato sauce, crushed tomatoes or even a homemade tomato puree can work. You can also use a mixed marinara for extra flavor.
Fresh Parsley: Don’t have parsley? Chopped green onions or basil can be a good substitute for garnish, adding a fresh kick!
What’s the Best Way to Cook Ground Beef for This Dish?
Cooking ground beef just right is key for this recipe! Start by preheating your skillet and adding olive oil. Here’s how you do it:
- Use medium heat to avoid burning. If it’s too high, the beef could sear too quickly.
- Once you add the beef, break it apart gently with a spoon. Allow it to evenly brown, around 5-7 minutes.
- Don’t forget to drain excess fat! This keeps the dish from being greasy.
Following these steps ensures your beef is tender and flavorful, making your Cajun Beef Spaghetti dish really shine!

How to Make Cajun Beef Spaghetti
Ingredients You’ll Need:
- 12 oz (340g) spaghetti
- 1 lb (450g) ground beef
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 1 cup tomato sauce
- 1/2 cup beef broth or water
- 2 tbsp olive oil
- 1 tbsp Cajun seasoning (blend of paprika, cayenne, garlic powder, onion powder, oregano, thyme, salt, and pepper)
- 1/2 tsp smoked paprika (optional for extra smokiness)
- 1/4 tsp crushed red pepper flakes (optional, adjust to heat preference)
- Salt and freshly ground black pepper to taste
- Fresh parsley, chopped (for garnish)
- Grated Parmesan cheese (for garnish)
How Much Time Will You Need?
This delicious meal takes about 25-30 minutes from start to finish. You’ll spend around 10-15 minutes prepping and cooking, plus there’s no long simmering time—just a quick mix of flavors, and you’re ready to eat! Perfect for a busy weeknight dinner!
Step-by-Step Instructions:
1. Boil the Spaghetti:
Start by bringing a large pot of salted water to a boil. Cook the spaghetti according to the package instructions until it’s al dente—this means it should still have a little bite to it. Once it’s done, drain well and set aside.
2. Sauté the Vegetables:
While the pasta is cooking, heat the olive oil in a large skillet over medium heat. Toss in the chopped onion and sauté for about 3 minutes until it softens. Don’t forget the garlic! Add the minced garlic and cook for another 30 seconds until it releases that lovely aroma.
3. Cook the Beef:
Now, add the ground beef to the skillet. Break it apart with a spoon and cook until it’s browned and no longer pink, which should take about 5-7 minutes. If there’s any excess fat, make sure to drain it out for a healthier dish.
4. Season It Up:
Sprinkle the Cajun seasoning, smoked paprika, crushed red pepper flakes, salt, and pepper over the beef. Stir everything together for about 1-2 minutes; this helps toast the spices and really brings out their flavors!
5. Pour in the Sauce:
Now it’s time for the sauce! Pour in the tomato sauce and beef broth, stir well, and bring everything to a gentle simmer. Let it simmer for about 5-7 minutes so the flavors can meld and the sauce thickens up a bit.
6. Combine with the Pasta:
Finally, add the cooked spaghetti straight into the skillet with the beef sauce. Toss everything together really well, ensuring that every strand of pasta is coated with that spicy Cajun mixture.
7. Serve and Garnish:
Now it’s time to serve! Plate the delicious Cajun Beef Spaghetti and garnish it with a sprinkle of grated Parmesan cheese and some fresh chopped parsley for a touch of color and flavor. Enjoy every bite of this spicy and comforting dish!
Can I Use a Different Type of Meat?
Absolutely! Ground turkey or chicken can be great substitutes for a leaner option. Just remember that these meats may have a milder flavor, so you might want to adjust the seasoning slightly.
How Can I Adjust the Spice Level?
If you’re looking for a milder version, reduce the amount of Cajun seasoning or omit the crushed red pepper flakes. You can always serve hot sauce on the side for those who like a kick!
Can I Make This Dish Ahead of Time?
You bet! You can prepare the sauce and cook the beef ahead of time. Simply store it in the fridge for up to 3 days. When ready to enjoy, reheat the sauce and toss with freshly cooked spaghetti.
What’s the Best Way to Store Leftovers?
Store any leftovers in an airtight container and keep them in the fridge for up to 3 days. To reheat, gently warm on the stove or microwave, adding a splash of water or broth if the sauce is too thick.
