Ingredients
Method
- Prep the zoodles: Spiralize the zucchini and set in a colander. Sprinkle with a pinch of salt and let sit 10 minutes to draw out water. Pat dry with paper towels. This helps prevent a watery sauce.
- Season the shrimp: Pat shrimp dry. Toss with a little salt, pepper, and a drizzle of olive oil.
- Sear the shrimp: Heat a large skillet over medium-high. Add 1 tablespoon butter and the olive oil. Cook shrimp 1–2 minutes per side until just pink and opaque. Transfer to a plate. Don’t overcook.
- Sauté the garlic: Lower heat to medium. Add remaining 2 tablespoons butter. Stir in garlic and cook 30–45 seconds until fragrant, not browned.
- Build the Alfredo base: Pour in heavy cream and bring to a gentle simmer. Whisk in cream cheese until smooth and melted.
- Add Parmesan: Reduce heat to medium-low. Whisk in Parmesan a handful at a time until the sauce thickens slightly and coats the back of a spoon. Season with salt, pepper, and red pepper flakes.
- Brighten it up: Add lemon zest and a small squeeze of lemon juice if using. Taste and adjust salt or pepper.
- Warm the zoodles: Add the zoodles to the skillet. Toss gently for 1–2 minutes just until heated and slightly tender. Do not overcook or they’ll release too much water.
- Finish with shrimp: Return shrimp and any juices to the pan. Toss to coat in sauce and warm through, about 1 minute.
- Serve: Top with parsley and extra Parmesan. Serve immediately while the sauce is velvety and the zoodles still have bite.

How to Make It
- Prep the zoodles: Spiralize the zucchini and set in a colander. Sprinkle with a pinch of salt and let sit 10 minutes to draw out water. Pat dry with paper towels.
This helps prevent a watery sauce.
- Season the shrimp: Pat shrimp dry. Toss with a little salt, pepper, and a drizzle of olive oil.
- Sear the shrimp: Heat a large skillet over medium-high. Add 1 tablespoon butter and the olive oil.
Cook shrimp 1–2 minutes per side until just pink and opaque. Transfer to a plate. Don’t overcook.
- Sauté the garlic: Lower heat to medium.
Add remaining 2 tablespoons butter. Stir in garlic and cook 30–45 seconds until fragrant, not browned.
- Build the Alfredo base: Pour in heavy cream and bring to a gentle simmer. Whisk in cream cheese until smooth and melted.
- Add Parmesan: Reduce heat to medium-low.
Whisk in Parmesan a handful at a time until the sauce thickens slightly and coats the back of a spoon. Season with salt, pepper, and red pepper flakes.
- Brighten it up: Add lemon zest and a small squeeze of lemon juice if using. Taste and adjust salt or pepper.
- Warm the zoodles: Add the zoodles to the skillet.
Toss gently for 1–2 minutes just until heated and slightly tender. Do not overcook or they’ll release too much water.
- Finish with shrimp: Return shrimp and any juices to the pan. Toss to coat in sauce and warm through, about 1 minute.
- Serve: Top with parsley and extra Parmesan.
Serve immediately while the sauce is velvety and the zoodles still have bite.
Keeping It Fresh
- Storage: Store leftovers in an airtight container in the fridge for up to 2 days. The zoodles will soften but the flavor holds.
- Reheating: Warm gently in a skillet over low heat. Add a splash of cream to loosen the sauce.
Avoid microwaving for too long; it toughens shrimp.
- Make-ahead tips: Spiralize zucchini up to 24 hours ahead and store on paper towels in a sealed container. Grate Parmesan and prep garlic in advance. Cook shrimp and sauce fresh for best texture.
Health Benefits
- Lower carbs: Zucchini replaces pasta, keeping net carbs low while still delivering volume and satisfaction.
- High-quality protein: Shrimp is lean, with essential amino acids and minerals like selenium and iodine.
- Healthy fats: Butter and cream provide fats that help with satiety on keto.
Parmesan adds calcium and protein.
- Vegetable boost: Zucchini brings fiber, potassium, and antioxidants with very few calories.
What Not to Do
- Don’t overcook the shrimp: They turn rubbery fast. Pull them off the heat as soon as they turn pink.
- Don’t skip drying the zoodles: Excess moisture waters down the sauce and dulls the flavor.
- Don’t boil the sauce hard: Vigorous boiling can split dairy. Keep it to a gentle simmer for a silky texture.
- Don’t use pre-shredded Parmesan if you can avoid it: Anti-caking agents prevent smooth melting.
Freshly grated melts cleaner.
- Don’t overcrowd the pan: Cook shrimp in batches if needed to get a proper sear.
Recipe Variations
- Garlic mushroom Alfredo: Sauté sliced mushrooms in butter before adding garlic. Their savory flavor deepens the sauce.
- Spinach Alfredo: Stir in a couple handfuls of baby spinach to wilt just before adding the shrimp back.
- Lemon-pepper twist: Use extra lemon zest and cracked black pepper for a brighter profile.
- Cajun kick: Toss shrimp with Cajun seasoning before searing and add a pinch to the sauce.
- Bacon boost: Crisp a few strips of bacon first, cook the shrimp in the bacon fat, and crumble bacon over the top.
- Dairy-light option: Swap half the cream for unsweetened almond milk and add an extra ounce of cream cheese to maintain body.
FAQ
Can I use frozen shrimp?
Yes. Thaw completely in the fridge or under cold running water, then pat very dry before cooking so they sear instead of steaming.
How do I keep zoodles from getting soggy?
Salt and drain them first, pat dry, and only warm them briefly in the sauce.
High heat for a short time works better than slow cooking.
What can I substitute for zucchini?
Yellow squash zoodles work well. For ultra-low carb, try shirataki noodles, but dry them thoroughly in a hot pan before saucing.
Is this recipe gluten-free?
Yes, as written it’s naturally gluten-free. Just make sure your Parmesan and seasonings don’t have any hidden additives.
Can I make this without cream cheese?
You can.
Simmer the cream a bit longer to reduce and thicken, and add a little extra Parmesan to help the sauce cling.
What goes well on the side?
A simple green salad with lemon vinaigrette, roasted asparagus, or garlicky sautéed broccoli keeps it light and balanced.
How many carbs are in a serving?
It varies with zucchini size and cheese amounts, but it typically lands around 6–8 net carbs per serving. Check your specific ingredients to be sure.
Can I use chicken instead of shrimp?
Absolutely. Use thinly sliced chicken breast or thighs.
Cook through before you start the sauce, then proceed as directed.
