Cajun Chicken & Roasted Red Pepper Fettuccine Alfredo
This is my go-to date-night pasta — creamy fettuccine Alfredo with seared cubes of seasoned chicken and sweet roasted red peppers folded right through it. The trick is that everything but the noodles happens in one skillet: I sear the chicken, toss in the peppers, then build the whole sauce in the same pan so it picks up all that flavor. I keep the heat gentle in the sauce so the kids will eat it, then leave a shaker of Cajun on the table for anyone who wants to kick it up. Serve it with garlic bread and you've got a real spread.
The video for this one is a full start-to-finish walkthrough — I gather every ingredient on camera, cube the chicken while the pasta's boiling, then build everything else in the skillet — because a from-scratch Alfredo sounds like restaurant territory, and honestly it's pretty easy and simple once you watch it happen. Pay attention to the cream when you watch: I bring it to a simmer and let it loosen before any seasoning goes in, then mix it in well so there are no lumps.
The other habit I push in the video is tasting as you go: I taste the sauce as soon as the seasoning is stirred in, adjust to preference, and hit mine with a little extra lemon pepper near the end. Cook it that way and it comes out right on your stove, for your table.

The recipe
Cajun Chicken & Roasted Red Pepper Fettuccine Alfredo
Ingredients
- 1 pound fettuccine pasta (cooked to package directions, about 12–13 minutes)
- 2 chicken breasts, cut into bite-size cubes
- olive oil, for the chicken and the pan
- 2 teaspoons salt (per chicken breast)
- Cajun seasoning, for the chicken
- black pepper, for the chicken
- minced garlic, for searing with the chicken
- roasted red peppers, drained and sliced into strips
- about 1 to 1 1/2 cups cream, for the sauce
- lemon pepper seasoning, for the sauce
- garlic powder, for the sauce
- onion powder, for the sauce
- salt, for the sauce, to taste
- fresh grated Parmesan cheese (or pre-grated), as much as you like
- fresh or dried parsley, for the sauce and garnish
- garlic bread, for serving (optional)
How to Make It
- Bring a large pot of water to a boil, add the fettuccine, and cook to package directions (about 12–13 minutes), stirring so the noodles don't stick; drain and set aside.
- While the pasta cooks, cut each chicken breast into even bite-size cubes.
- Drizzle the cubed chicken with olive oil and rub to coat.
- Season the chicken all over with salt, Cajun seasoning, and black pepper.
- Heat a drizzle of olive oil in a large skillet over medium-high heat.
- Add the seasoned chicken and a little minced garlic and sear, stirring, until browned and cooked through.
- Add the sliced roasted red peppers and toss with the chicken for a minute or two.
- Pour the cream directly into the same skillet over the chicken and peppers and bring to a simmer to loosen it.
- Stir in the lemon pepper, garlic powder, onion powder, and salt until smooth and lump-free.
- Taste and adjust the seasoning — add Cajun here if you want more heat, though I skip it in the sauce so the kids can eat it.
- Stir in the Parmesan until melted and the sauce is smooth (fresh grated melts best; packaged can come out clumpy).
- Stir in the parsley and let the sauce thicken slightly.
- Add the drained fettuccine to the skillet and toss until the noodles are coated and the chicken and peppers are mixed throughout (add a splash more cream for creamier noodles, and re-season to taste).
- Turn off the heat, plate the pasta, finish with extra Parmesan and a little parsley, and serve with garlic bread on the side.
Curtis's Tips
- Cut the chicken into even cubes so the pieces sear and cook at the same rate.
- Olive oil isn't just a binder for the seasoning — it really helps the texture of the chicken.
- Wash your hands before touching the chicken or the olive oil to avoid cross-contamination.
- Bring the cream to a simmer to loosen it up before adding any seasoning.
- I skip Cajun seasoning in the sauce because my kids don't eat spicy — add Cajun to taste for more heat.
- Use fresh grated Parmesan for the best melt; packaged grated has a film that makes it clumpy.
- You can always add more cream for creamier noodles — just taste and re-season if you do.
- Parsley garnish is optional; fresh or dried both work. Plate it as a date-night dish with garlic bread on the side.
Why this works
The sauce gets built right on top of the seared chicken and roasted red peppers — the cream goes into the same hot skillet, so everything already in that pan flavors the sauce. That's why the seasoning is split: salt and Cajun live on the chicken, while the sauce gets its own mix of lemon pepper, garlic powder, onion powder, and salt — so the sauce stays mild enough for the kids while the heat stays on the chicken, and anyone who wants more can add Cajun at the table. Order matters too: loosen the cream at a simmer before the seasoning goes in, or you'll chase lumps, and the cheese joins only once the base already tastes right.
- Olive oil — not just a binder for the seasoning; it really helps the texture of the chicken.
- Roasted red peppers — they get a minute or two in the skillet with the chicken before the cream goes in, so their sweetness ends up in every bite instead of sitting on top.
FAQ
How much cream do you actually use?
One cup is the baseline, but in the video I pour closer to a cup and a half because I like my noodles creamier. If you go heavier on the cream, it's okay to add more seasoning too; keep tasting until it's back where you want it. You can even add a splash once the pasta's already in the skillet.
Is this too spicy for kids?
Not the way I make it — my kids don't eat spicy, so no Cajun goes into the sauce at all. The sauce is just lemon pepper, garlic powder, onion powder, and salt; the Cajun stays on the chicken, which keeps the flavor without lighting anybody up. If your table wants heat, taste the sauce and stir Cajun straight into the pan.
Why did my sauce come out clumpy?
Check your cheese first. Packaged grated Parmesan comes with a film over it that makes it very hard to melt — that's exactly how a sauce goes clumpy, and it's why fresh grated gets you the best results. It melts in smooth and the sauce stays that way.
My sauce looks thin — did I mess it up?
Probably not — this sauce thickens late. When the cream first hits the skillet it's supposed to be loose; that's the point of bringing it to a simmer. It doesn't start visibly tightening until the Parmesan has melted in and the parsley is stirred through, right before the pasta goes in. Keep it simmering and give it that time before you judge it.
