You’ll get restaurant flavor with everyday ingredients and about 30 minutes of cooking time.
Ingredients
Method
- Prep the shrimp: Pat the shrimp very dry with paper towels. Season with salt and pepper. This helps them sear instead of steam.
- Get your noodles ready: If using zucchini, sprinkle lightly with salt and let them sit in a colander for 10 minutes, then pat dry. If using shirataki, rinse well, boil for 2 minutes, then dry in a hot skillet for 3–4 minutes to remove excess moisture.
- Sear the shrimp: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add half the shrimp in a single layer. Cook 1–2 minutes per side until just pink and opaque. Remove to a plate and repeat with remaining shrimp. Do not overcook.
- Build the sauce base: Reduce heat to medium. Add butter and remaining 1 tablespoon olive oil to the skillet. Add garlic and cook 30 seconds until fragrant. If using wine or broth, pour it in and simmer 1–2 minutes, scraping up browned bits.
- Make it creamy: Stir in heavy cream. Bring to a gentle simmer (not a hard boil). Add Parmesan a handful at a time, stirring until melted and smooth. Season with salt, pepper, nutmeg, red pepper flakes, lemon zest, and lemon juice. Adjust to taste.
- Add greens: Stir in spinach or kale until just wilted, about 1 minute.
- Combine smartly: Return shrimp to the pan and toss to coat. If meal-prepping, do not add zucchini noodles to the sauce in the pan. Instead, portion noodles into containers and spoon the shrimp Alfredo over the top. This prevents sogginess.
- Garnish and portion: Top with extra Parmesan and parsley. Let cool slightly before sealing containers.
Why This Recipe Works
- Quick-cooking protein: Shrimp cooks in minutes, so you spend less time at the stove and avoid overcooked meat in your lunch containers.
- Low-carb swap: Zucchini noodles or shirataki noodles stand in for pasta, soaking up the sauce without the carbs or heaviness.
- Rich, satisfying sauce: Heavy cream, butter, and Parmesan keep you full and help you stay on track with keto macros.
- Flexible and forgiving: You can use frozen shrimp, adjust garlic, or swap veggies without ruining the dish.
- Meal-prep friendly: The sauce reheats well, and the components keep their texture if you follow a few simple steps.
Ingredients
- 1.5 pounds large shrimp, peeled and deveined (tails optional)
- 2 tablespoons olive oil, divided
- 2 tablespoons unsalted butter
- 4 cloves garlic, minced
- 1 cup heavy cream
- 3/4 cup freshly grated Parmesan cheese (plus extra for serving)
- 1/4 teaspoon nutmeg (optional, but classic)
- 1 teaspoon lemon zest, plus 1 tablespoon lemon juice
- 1/4 cup dry white wine or low-sodium chicken broth (optional, for deglazing)
- 1/2 teaspoon crushed red pepper flakes (optional)
- 3 medium zucchini, spiralized into noodles (or 4 packs shirataki noodles, rinsed and dried)
- 1 cup baby spinach or chopped kale
- Salt and black pepper, to taste
- Fresh parsley, chopped, for garnish
Instructions
- Prep the shrimp: Pat the shrimp very dry with paper towels. Season with salt and pepper. This helps them sear instead of steam.
- Get your noodles ready: If using zucchini, sprinkle lightly with salt and let them sit in a colander for 10 minutes, then pat dry.
If using shirataki, rinse well, boil for 2 minutes, then dry in a hot skillet for 3–4 minutes to remove excess moisture.
- Sear the shrimp: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add half the shrimp in a single layer. Cook 1–2 minutes per side until just pink and opaque.
Remove to a plate and repeat with remaining shrimp. Do not overcook.
- Build the sauce base: Reduce heat to medium. Add butter and remaining 1 tablespoon olive oil to the skillet.
Add garlic and cook 30 seconds until fragrant. If using wine or broth, pour it in and simmer 1–2 minutes, scraping up browned bits.

If meal-prepping, do not add zucchini noodles to the sauce in the pan. Instead, portion noodles into containers and spoon the shrimp Alfredo over the top. This prevents sogginess.
- Garnish and portion: Top with extra Parmesan and parsley.
Let cool slightly before sealing containers.
How to Store
- Fridge: Store in airtight containers for up to 3–4 days. Keep noodles and sauce together if you followed the portioning step above; they’ll hold up well if noodles were dried properly.
- Freezer: The sauce and shrimp freeze better without zucchini. Freeze just the shrimp Alfredo in a freezer-safe container for up to 2 months.
Add fresh zucchini or shirataki when reheating.
- Reheating: Microwave at 50–60% power in 60–90 second bursts, stirring between, until warmed through. Or reheat gently in a skillet over low heat with a splash of cream or water to loosen the sauce.
Why This is Good for You
- Low in carbs, high in satisfaction: Zucchini or shirataki noodles keep net carbs low while the creamy sauce curbs cravings.
- Protein-rich: Shrimp delivers lean protein with minimal calories and cooks fast, making it easy to stick to your plan.
- Healthy fats: Butter, cream, and Parmesan provide fats that support keto while keeping you full longer.
- Micronutrient boost: Spinach or kale adds potassium, magnesium, and vitamin K—key nutrients that many keto eaters need more of.
What Not to Do
- Don’t overcook the shrimp: They turn rubbery quickly. Pull them as soon as they’re pink and just opaque.
- Don’t skip drying the noodles: Extra moisture will water down your sauce and make the meal soggy.
- Don’t boil the cream hard: A gentle simmer keeps the sauce smooth.
A rolling boil can split it.
- Don’t rely on pre-shredded Parmesan: It often has anti-caking agents that prevent melting. Freshly grated works best.
- Don’t add lemon too early: Add zest and juice after the cream has thickened so the sauce doesn’t curdle.
Variations You Can Try
- Broccoli Alfredo: Swap greens for small broccoli florets. Steam or sauté until crisp-tender before adding to the sauce.
- Cajun Shrimp Alfredo: Season shrimp with Cajun seasoning and skip red pepper flakes.
Add a squeeze of lemon at the end.
- Mushroom Alfredo: Sauté sliced cremini mushrooms before making the sauce for a deeper, savory flavor.
- Bacon twist: Cook 3–4 slices of bacon until crisp. Use some of the rendered fat in the sauce and crumble bacon on top.
- Dairy-light option: Use half heavy cream and half unsweetened coconut cream. Flavor with extra Parmesan and a pinch of xanthan gum to help thicken if needed.
- Different “noodles”: Try spaghetti squash strands or hearts-of-palm pasta for variety.
FAQ
Can I use frozen shrimp?
Yes.
Thaw overnight in the fridge or run under cold water for 5–7 minutes, then pat very dry. Wet shrimp won’t sear well and will dilute your sauce.
How can I thicken the Alfredo sauce without flour?
Simmer gently to reduce, then whisk in more Parmesan a little at a time. You can also add a tiny pinch of xanthan gum (about 1/8 teaspoon), whisked in slowly, to thicken without carbs.
What’s the best noodle option for meal prep?
Shirataki noodles hold their texture the best over several days.
Zucchini noodles are great if you salt, drain, and dry them well—but they’re best within 2–3 days.
Can I make this without wine?
Absolutely. Use low-sodium chicken broth or skip the deglazing step. The sauce will still be rich and flavorful thanks to garlic, cream, and Parmesan.
Is this spicy?
Only if you add red pepper flakes or Cajun seasoning.
If you’re serving kids or prefer mild flavors, leave those out and finish with lemon and parsley instead.
How many servings does this make?
This recipe makes 4 meal prep portions. If you need more, it scales well—just use a wider skillet so the shrimp still sear instead of steam.
Can I use chicken instead of shrimp?
Yes. Slice chicken thighs or breasts thinly, season, and cook fully before making the sauce.
Chicken will take longer than shrimp, so plan for a few extra minutes.
