Ingredients You’ll Need for Keto Shrimp Alfredo
Gather your squad. Most of this is probably already in your kitchen, masquerading as ordinary items about to become extraordinary.
- Raw Shrimp (1 lb): Peeled and deveined. Get the big ones—size matters here for that juicy bite. Tail-on or off is your call, but tails are just fancy handles for eating with your hands later.
- Heavy Cream (1 cup): This is the non-negotiable base of our creamy dreamy sauce. Don’t even think about substituting milk; it will weep and break.
- Parmesan Cheese (1 cup, freshly grated): I’m begging you, do not use the dusty stuff from the green canister. Get a block and grate it yourself. It melts so much better and won’t turn your sauce into a grainy mess.
- Butter (2 tbsp): Salted or unsalted, I’m not your boss. We’ll use this for cooking the shrimp and building our sauce.
- Cream Cheese (2 oz): This is our secret weapon for next-level creaminess and helping the sauce thicken up like a champ.
- Garlic (3 cloves, minced): Because Alfredo sauce without garlic is just sad, warm cream.
- Chicken or Vegetable Broth (1/4 cup): This helps thin the sauce just enough without diluting the flavor.
- Konjac Noodles (or Zoodles): Your choice! I used a 12oz bag of konjac (shirataki) noodles, rinsed and drained. If you’re team zucchini, spiralize 2-3 medium zucchinis.
- Seasoning Squad: Paprika, Italian seasoning, salt, and black pepper. Maybe a pinch of red pepper flakes if you like a little ~drama~.
Step-by-Step Instructions
- Prep Your Noodles. If using konjac noodles, open the bag, give them a good rinse under cold water (trust me, it’s necessary), and pat them very dry with a paper towel. For zoodles, just spiralize and set aside. We’ll deal with them later.
- Cook the Shrimp. Heat a large skillet over medium-high heat. Add 1 tbsp of butter. Season your shrimp with paprika, salt, and pepper. Once the butter is sizzling, add the shrimp in a single layer. Cook for about 1-2 minutes per side until they’re pink and opaque. Don’t overcook them, or they’ll turn into rubbery little erasers. Remove them from the skillet and set aside.
- Build the Sauce. In the same skillet (all those yummy shrimp bits are still in there!), melt the remaining 1 tbsp of butter. Add the minced garlic and cook for about 30 seconds until it’s fragrant—don’t let it burn!
- Make it Creamy. Pour in the chicken broth to deglaze the pan, scraping up all the browned bits. Then, add the heavy cream and cream cheese. Whisk it all together until the cream cheese is fully melted and the sauce is smooth.
- Cheese, Please! Reduce the heat to low. Slowly whisk in your freshly grated Parmesan cheese until it’s completely melted into the sauce. Let it simmer for 2-3 minutes until it thickens up nicely. Season with Italian seasoning, salt, and pepper to taste.
- Bring It All Home. Toss your prepared noodles (konjac or zoodles) into the sauce to heat through. If you’re using zoodles, just toss them for a minute—you want them warm but still with a bit of a bite (al dente, but for veggies). Finally, add the cooked shrimp back to the skillet and stir to coat everything in that glorious sauce.
- Serve Immediately. Garnish with a little more Parmesan and some fresh parsley if you’re feeling fancy. Dig in before anyone else does.
Common Mistakes to Avoid
- Using Pre-Shredded Cheese: I said it once, I’ll scream it from the rooftops. The anti-caking agents in bagged cheese will make your sauce grainy and sad. Just grate the cheese.
- Overcooking the Shrimp: They cook in, like, two minutes. The second they curl up and turn pink, they’re done. Walk away and you’ll be eating seafood jerky.
- Not Draining Konjac Noodles Well: These noodles are packed in water. If you don’t rinse and dry them thoroughly, they can make your sauce watery. A quick dry-fry in a separate pan (no oil) after rinsing is a pro-move to eliminate any extra moisture.
- Boiling the Sauce: Keep the heat low when you add the cheese. If the sauce boils too aggressively, the fat can separate, and you’ll have a oily puddle. A gentle simmer is your BFF.
Alternatives & Substitutions
No shrimp? No problem. Swap it for grilled chicken, scallops, or even just load it up with broccoli. Vegetarian? Skip the seafood and use the same veggies.
Dairy is not your friend? Full-fat canned coconut milk can stand in for the heavy cream in a pinch, and nutritional yeast can provide a cheesy flavor, though the texture will be different.
Out of cream cheese? Mascarpone is a glorious, even richer substitute. If you must, a little extra Parmesan can help thicken things up.
FYI, the sauce is the star. You can put it on literally anything—cauliflower rice, steamed veggies, or just eat it with a spoon. I won’t judge.
FAQs about Keto Shrimp Alfredo
Can I use frozen shrimp?
Absolutely! Just thaw them completely in the fridge first. Cooking frozen shrimp straight from the freezer will make them release a ton of water and steam instead of sear. Pat them very dry with paper towels before seasoning.
My sauce is too thin! Help!
Don’t panic! Let it simmer on low for a few more minutes; it will thicken as it reduces. If you’re really in a rush, a tiny pinch of xanthan gum (like 1/8 tsp) whisked in will work miracles.
My sauce is too thick!
Easy fix! Just whisk in a little more chicken broth or cream, one tablespoon at a time, until it reaches your desired consistency.
Are konjac noodles… weird?
They have a different texture—a bit more chewy and gelatinous than pasta. Rinsing them well is key! IMO, they’re a fantastic vehicle for sauce when you’re craving a noodle experience. If you’re skeptical, zoodles are always a fantastic, fresh alternative.
How long do leftovers last?
Store them in an airtight container in the fridge for up to 2 days. Be aware that the sauce may separate a bit upon reheating. Gently warm it in a skillet on low heat, adding a splash of cream or broth to bring it back to life.
Can I make this ahead of time?
You can make the sauce ahead of time! Store it separately and gently reheat it on the stove, then add freshly cooked shrimp and your noodles of choice. This prevents everything from getting mushy.
