Ingredient Substitutions & Notes
No ground beef? Swap in ground turkey or chicken. For a lighter sauce, use half-and-half instead of heavy cream. Gluten-free pasta works great too! Freshly grated Parmesan melts smoother than pre-shredded, but either works in a pinch. Adjust the Cajun seasoning to your spice tolerance – start with less and add more if needed!

How to Make Creamy Cajun Beef Spaghetti with Three Cheese Parmesan Sauce
Okay, let’s get cooking! This creamy Cajun beef spaghetti comes together so fast once you get going. Just follow these simple steps, and you’ll have a flavor-packed meal ready in no time.
Step 1: Cook the Pasta
First things first – get that pasta water boiling! Salt it generously (it should taste like seawater) and cook your spaghetti al dente according to package directions. Here’s my little secret: reserve about 1/2 cup of that starchy pasta water before draining – it’s liquid gold for adjusting your sauce later!
Step 2: Brown the Cajun Beef
While the pasta cooks, heat olive oil in a large skillet over medium heat. Add those diced onions and let them soften until they’re translucent – about 3 minutes. Now add the minced garlic (don’t add it too soon or it’ll burn!) and stir for just 30 seconds until fragrant. Crumble in your ground beef, breaking it up into small pieces as it browns. Once no pink remains, sprinkle that Cajun seasoning all over and stir well to coat every little crumble.
Step 3: Make the Three Cheese Sauce
Now for the magic! Pour in the heavy cream and let it warm through for about a minute. Reduce heat to low – this is important so your cheese doesn’t get grainy. Start adding your cheeses gradually: Parmesan first, then cheddar, then mozzarella, stirring constantly until each addition melts into creamy perfection. If the sauce seems too thick, add splashes of that reserved pasta water until it’s luxuriously silky.
Step 4: Combine and Serve
Time for the grand finale! Add your drained spaghetti to the skillet and gently toss until every strand is coated in that dreamy sauce. Serve immediately with extra Parmesan grated over the top – because let’s be honest, there’s no such thing as too much cheese!

Tips for Perfect Creamy Cajun Beef Spaghetti
Here are my tried-and-true tricks for nailing this dish every time:
- Spice control: Start with 1 tbsp Cajun seasoning and taste before adding more – you can always increase the heat but can’t take it away!
- Pasta water power: That starchy reserved water isn’t just for thinning – it helps the creamy sauce cling perfectly to each spaghetti strand.
- Beef basics: Cook the beef just until no pink remains – overcooking makes it dry and tough against that luscious sauce.
- Cheese magic: Take it off the heat when adding cheese to prevent separation – residual heat will melt it beautifully.
Serving Suggestions for Creamy Cajun Beef Spaghetti
This creamy Cajun beef spaghetti is a star on its own, but a few simple sides can take it to the next level. I love pairing it with warm, buttery garlic bread to soak up every bit of that luscious sauce. A crisp green salad with a tangy vinaigrette balances the richness perfectly. If you have leftovers (lucky you!), reheat them gently on the stove with a splash of cream to bring the sauce back to life. Trust me, it’s just as good the next day!
Storage & Reheating
Here’s how to keep your creamy Cajun beef spaghetti tasting amazing: Store leftovers in an airtight container in the fridge for up to 3 days. When reheating, go low and slow on the stove with a splash of milk or cream to revive that luscious sauce texture. I don’t recommend freezing this one – cream sauces tend to separate when thawed, and we want to keep all that cheesy goodness perfectly creamy!

FAQs About Creamy Cajun Beef Spaghetti
Got questions? I’ve got answers! Here are the most common things people ask me about this creamy Cajun beef spaghetti:
Can I use pre-shredded cheese?
Technically yes, but fresh grated melts smoother! Pre-shredded has anti-caking agents that can make your sauce slightly grainy. If that’s all you’ve got, just melt it extra slowly on low heat.
How spicy is this?
It’s got a nice kick, but totally adjustable! Start with 1 tbsp Cajun seasoning and taste before adding more. Remember – you can always add heat but can’t take it away once it’s in there!
Can I add veggies?
Absolutely! Bell peppers sautéed with the onions are fantastic. Mushrooms, zucchini, or spinach would work too – just cook them down before adding the beef. More veggies = more flavor and nutrition!
