🔪 How to Make Creamy Shrimp Alfredo

Start by heating a large skillet on medium heat. Add in the olive oil and the shrimp.  

Sauté them for a few minutes until they are just turning pink, then remove them and set aside.

Add the butter and once melted, add in the minced garlic, then sauté it for about 20 seconds, making sure not to brown it.

Add in the mascarpone cheese.

Once that has melted, pour in the heavy cream, salt and ground black pepper.

Add in the parmesan cheese, and simmer for 5-7 minutes or until thickened.

Add in the Palmini noodles and toss in the sauce.

Top with the shrimp and it's ready to serve.

☑️ Storage Instructions

Store leftovers in an airtight container for up to 3 days. Reheat gently over low heat, adding a splash of cream if needed. I do not recommend freezing this dish. The textures just do not hold up well once frozen, thawed and reheated.

🍴 What to Serve with Gluten-Free Shrimp Alfredo

• Cheesy Roasted asparagus
• Caprese Salad
• Caesar salad with homemade Caesar Dressing
• Keto Italian Breadsticks or Dinner Rolls
• Roasted Brussels Sprouts or a medley of Oven Roasted Veggies

💡 Tips

• Use fresh or frozen shrimp: Use what you can find on sale. If using frozen, thaw them under cold running water for a few minutes before cooking.

• Don’t overcook the shrimp: They only need a few minutes over medium heat until they turn pink and opaque.

• Palmini pro tip: Rinse the hearts of palm noodles well and let them soak in cream for 15 minutes to mellow the flavor.

• Let the sauce thicken: Simmer the Alfredo sauce until it coats the back of a spoon for that perfect creamy consistency.

• Use freshly grated parmesan cheese: Pre-grated cheese often contains anti-caking agents that can make the sauce grainy.

🔄 Substitutions and Additions

• Make it spicy: A dash of red pepper flakes or hot sauce adds a little heat and depth to the sauce.

• Add veggies: Sautéed mushrooms, spinach, or roasted asparagus are great low-carb additions.

• Swap the protein – Chicken, scallops, or even salmon work beautifully in this dish.

• Try a different noodle: Zucchini noodles or spaghetti squash make great alternatives to Palmini.

• Extra cheesy: A sprinkle of shredded mozzarella or a bit of cream cheese in the sauce makes it even more indulgent.

• Brighten it up: A squeeze of fresh lemon juice at the end balances the richness.

• Herbs: Fresh parsley or basil adds a little freshness to the finished dish.

• Garlic lovers: Add an extra clove or two for even more garlicky goodness.

Are There Carbs in Shrimp?

Can I Use Pre-Cooked Shrimp?

You can, not uncooked works best. If you used cooked, only heat them briefly at the end so they don’t get rubbery.

Can I Make the Alfredo Sauce Ahead of Time?

Yes! Store it in the fridge for up to 3 days and reheat over low heat, stirring frequently.

How Do I Prevent the Sauce From Becoming Grainy?

Use freshly grated Parmesan and stir it in slowly over low heat to keep it smooth.

Tips for Buying Shrimp for Keto Shrimp Alfredo

• Look for fresh, domestic, wild-caught shrimp when available.
• If you have to buy frozen, look at the ingredients. It should just say, "shrimp and water."
• Though jumbo shrimp are my personal favorite, for this recipe, you'll want a pick a medium size, or 31-35 count. This ensures the perfect sauce to shrimp ratio.
• To make this recipe in a jiffy, select shrimp that have are already peeled and deveined. If you can't find them already peeled, look for ones that have been split down the spine. This makes peeling so much easier.
• Don't be afraid to ask to touch and smell the shrimp at your grocery store or fish market. You want to avoid shrimp with a strong "shrimpy," or ammonia-like smell or those with a slimy or soft texture.
