This Keto Shrimp Alfredo is an easy low-carb dinner perfect for a weeknight! This one-pan keto meal has just 2 net carbs per serving and is ready in about 10 minutes.
We love a good, quick keto dinner around here! Because we’re gluten-free, fast food isn’t really an option for us… So it’s important to have some super quick meals in our back pocket to keep away the “hangry” attitudes. A lot of times we’ll end the day with these Chicken Bacon Lettuce Wraps, but this time I wanted something more comforting, something to warm us up.
This Keto Shrimp Alfredo uses cooked, thawed shrimp, so really all you’re having to cook up is a delicious 5-ingredient alfredo sauce. It’s so smooth, creamy, and packed with parmesan cheese… I’d eat it with absolutely anything! You can even make a double or triple batch of this sauce and freeze for an even quicker dinner later!
I served this with my easy, quick Air Fryer Roasted Broccoli. It cooks in just 8 minutes, meaning it is incredibly easy to have a well-rounded, nutritious keto dinner with barely any work! You could substitute any other cooked protein in place of the shrimp for a convenient, go-to meal on the busiest weeknight.

How to cook shrimp:
This recipe uses cooked, thawed shrimp. You can likely find cooked frozen shrimp at the store, but there are several ways you can quickly cook shrimp if you are starting with raw shrimp. You can quickly sauté the shrimp in a pan with the method in this 20-Minute Cajun Shrimp recipe or you can grill it like in this Easy BBQ Shrimp recipe.
How to make Keto Shrimp Alfredo
This recipe is SO easy and perfect for a weeknight. Start by heating a large, deep skillet over medium heat, then add butter and melt. Add minced garlic and sauté about 30 seconds, getting it nice and fragrant but not burning.
Reduce heat to medium low and pour in the heavy cream. Stir until the mixture begins to bubble slightly, then add parmesan and Italian seasoning while you continue stirring. Add salt and pepper to taste and stir until the sauce becomes thick and creamy. Add cooked shrimp and cook 3-4 more minutes. Once the shrimp is heated throughout, serve immediately.
Can I use a different protein?
Yes, you could use any cooked protein in place of the shrimp! Add a pound of cooked chicken, steak, or whatever meat/protein you prefer for a quick one-pan alfredo dish. This 5-ingredient alfredo sauce recipe would be delicious with nearly anything!
How many carbs are in shrimp alfredo?
This recipe only has 2 net carbs for 1/4 of the sauce and a 1/4-pound of shrimp! It’s incredibly filling but low enough in carbs that you could go back for seconds if you’re super hungry!
This alfredo sauce on its own has 264 calories, 25.1 grams of fat, and 1.8 net carbs per serving.
What to serve with shrimp alfredo
This saucy one-pan dish goes with so many things! I served mine with crispy Roasted Broccoli for a filling, nutritious meal at about 5 net carbs total. The sauce was AMAZING with the broccoli! The whole meal took just 10 minutes, letting us enjoy a delicious low-carb dinner that didn’t taste at all like diet food.
You could also serve with Cacio e pepe Zoodles for a low-carb pasta feel under 5 net carbs. For a super impressive meal for guests around 8 net carbs total, serve your Shrimp Alfredo with Bacon-Wrapped Green Beans and Keto Bacon Cheddar Chive Biscuits!
Can I freeze keto alfredo sauce?
Yes, you can freeze this keto alfredo sauce! Allow it to cool completely, then transfer to a freezer bag or a jar (make sure to leave at least an inch of room so it’s able to expand). This sauce is best thawed and eaten within 3 months–It’s safe to eat after that, but the texture and taste isn’t as great if it’s in the freezer much longer.
If you shrimp was previously frozen, it’s probably best to not freeze it again. To meal prep this, I’d recommend cooking fresh shrimp and freezing it separately from the sauce. This is even more convenient because it allows you to use the shrimp for quesadillas, salads, tacos, and other dishes. Then you can use the alfredo sauce for a keto pizza sauce or with meal prepped chicken or pork chops!
