Why We Love Cajun Alfredo Sauce
Let’s talk about this white sauce first for a hot minute. It isn’t just for Instant Pot fettuccine alfredo noodles y’all. I mean think outside of the box already! This stuff is great on all the things. I mean the flavors are great right, and shouldn’t just stop at noodles. Vegetables with a drizzle of this on top brings them a lot of flavor, and creaminess.
You can layer with our vegetable lasagna with white sauce, toss with plain pasta, over chicken breast or drizzled on top of veggies. There are several options to adding heat as well, use what you love. Red pepper flakes are best; Cajun seasonings can be found with different flavor profiles, Sriracha brings an Asian flare and chili powder is a milder option.
Spicy Homemade Alfredo Sauce on Stove
Okay so you could buy bottled and then just add the spiciness right? I mean that is okay but if you have never made from scratch yet, don’t be scared. It is way easier than you might initially think and great because then you skip the preservatives for one. Secondly you can use dairy free products if that is needed and tweak it to your tastebuds.
Cajun Alfredo Sauce Ingredients
- 1 c heavy whipping cream
- 3 tbsp butter
- Freshly grated parmesan cheese
- Salt and pepper
- Ground coriander
- 1/3 tsp granulated garlic or garlic powder
- Minced garlic
- 1/8-1/2 tsp of cajun seasoning, cayenne pepper or red pepper flakes will work to add spice
You just need a pot on the stovetop to make this, or in our slow cooker chicken alfredo works too. If you’re in a tight space you could use a pressure cooker too using the saute function. In an RV or hotel room that may be all you have. When done pour on like pasta sauce, toss to coat and enjoy.
How to Make Dairy Free Alfredo Sauce
As I have mentioned before, my husband has needed lactose free foods for quite some time now. There is a way to make delicious dishes without it too I have found. In the stores you can find products all over with this option now which is great. You will learn that there is a great vegan plant based butter from Country Crock. Olive oil is an alternative but not nearly as good.
Coconut milk can be used for milks or creams. Parmesan hard cheeses are very low in lactose too, he hasn’t had issues with this in our experiences. The only tweak you may need to do is add a bit of cornstarch to thicken at the end. A little goes a long way, start with 1 tbsp and whisk until smooth with dairy free milk products.
If using the heavy cream listed below you won’t need that but alternatives aren’t as rich and thick so that is an addition you’ll likely want to make.
How to Make Alfredo Sauce with Cream
- Over medium high heat and add your butter.
- When melted turn heat down to low.
- Pour heavy cream into a saucepan.
- Then stir with a spatula until the two ingredients are combined.
- Add chopped garlic, as well as salt and spices to the saucepan, mix.
- After 2 minutes add shredded parmesan cheese to the sauce
Stir and cook for another five minutes or until warmed to your liking, and as thick as you’d like it to be. Another thickener that is a gluten free choice would be arrowroot. Works the same way but without the corn products so safe for those with celiac.
What can you put alfredo on other than fettuccini noodles?
I hope we explained this well. There is a printable recipe card at the bottom of this post too. If you are making this for spicy alfredo pasta, make the noodles separately unless you’re making something like our frozen chicken and noodles Instant Pot style.
To make cajun chicken pasta, boil your noodles in a pot of boiling water until al dente. Toss together once drained and let sit for a few minutes to let it further thicken and allow the noodles to really soak it up. If making cajun chicken alfredo without the carbs saute your meat and then slice before folding together. The smaller your pieces the more flavor it will absorb so remember that.
Another idea…..use veggie noodles instead!! That is right, for lower carb meals, make air fryer zoodles and this goes really well with that as well. Once again thinking way outside of the box but will surely become a new fave in your household.
If you need to make a cream based sauce more mild you can just add more heavy cream, that is pretty easy. Thinning it out with a bit of sweetness will do the trick too such as almond milk or even a splash of liquid sweetener. Start with just a bit, stir, taste, adjust again if needed.
