Keto Zucchini Shrimp Bake – A Creamy, Low-Carb Weeknight Favorite
This Keto Zucchini Shrimp Bake hits that sweet spot between comfort food and clean eating. It’s creamy, cheesy, and full of bright, garlicky shrimp without the carb-heavy pasta. Everything comes together in one baking dish, so cleanup is easy.
The flavors are fresh, the texture is satisfying, and the whole thing feels restaurant-worthy. If you’re looking for a simple, low-carb dinner that still tastes indulgent, this one delivers.
Ingredients
Method
- Prep the oven and pan. Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish with olive oil or nonstick spray.
- Slice the zucchini. Cut into thin rounds or use a peeler to make ribbons. Thinner slices cook faster and release less moisture in the final dish.
- Season the shrimp. Pat the shrimp dry. Toss with 1 tablespoon olive oil, 1/2 teaspoon salt, 1/4 teaspoon pepper, and Italian seasoning. Set aside.
- Make the creamy garlic base. In a skillet over medium heat, melt butter. Add garlic and cook 30–60 seconds until fragrant. Stir in heavy cream, lemon zest, and red pepper flakes. Simmer 1–2 minutes to thicken slightly. Turn off the heat and add half the Parmesan.
- Layer the vegetables. Arrange the zucchini in the baking dish. Drizzle with 1 tablespoon olive oil and a pinch of salt and pepper. This light seasoning keeps flavors bright.
- Add shrimp and sauce. Scatter the seasoned shrimp over the zucchini. Pour the creamy garlic mixture evenly on top. Sprinkle with mozzarella and the remaining Parmesan.
- Bake. Place on the center rack and bake for 12–15 minutes, until the shrimp are pink and just cooked and the cheese is melted and bubbling. Do not overbake—shrimp turns rubbery fast.
- Finish with lemon and herbs. Remove from the oven. Squeeze lemon juice over the top and let it rest for 3–5 minutes. Garnish with chopped parsley and extra Parmesan if you like.
- Serve. Spoon into bowls and enjoy as-is, or pair with a side salad or cauliflower rice for a fuller meal.
What Makes This Special
This bake leans on zucchini ribbons in place of pasta, which makes it feel light while still being hearty. Shrimp cooks fast and absorbs flavor, so you get a savory, garlicky bite in every forkful.
A touch of cream and cheese binds everything together without weighing it down. It’s also incredibly adaptable—swap herbs, add a kick of spice, or mix in other low-carb veggies. Best of all, it’s on the table in about 35 minutes.

How to Store
Let the bake cool to room temperature, then transfer to an airtight container. Refrigerate for up to 3 days. To reheat, warm gently in a 300°F (150°C) oven for 10–12 minutes, or microwave in short bursts to avoid overcooking the shrimp.
This dish doesn’t freeze well because zucchini holds water and shrimp can turn tough after thawing. If you must freeze, do so before baking and add cheese fresh when you’re ready to cook.
Health Benefits
- Low in carbs, high in protein: Shrimp provides lean protein without carbs, helping you stay full on a keto plan.
- Healthy fats for satiety: Olive oil, butter, cream, and cheese offer fats that support ketosis and keep cravings in check.
- Micronutrient boost: Zucchini brings vitamin C, potassium, and fiber; shrimp delivers selenium, iodine, and B12.
- Minimal sugar: No hidden sweeteners or starches, so it fits tightly into a low-carb lifestyle.
What Not to Do
- Don’t overbake the shrimp. Once they’re pink and opaque, you’re done. Extra time equals rubbery texture.
- Don’t skip salting the zucchini lightly. A pinch helps season the dish without making it watery.
- Don’t flood with cream. More cream sounds great but can make the bake soupy.
Stick to the listed amount.
- Don’t use pre-cooked shrimp. They’ll overcook in the oven and lose their tenderness.
- Don’t forget acid. Lemon brightens the richness and balances the cheese and cream.
Alternatives
- Veggie swaps: Sub part of the zucchini with sliced yellow squash or baby spinach. Broccoli florets work too, but pre-steam for 2–3 minutes.
- Dairy tweaks: Use all Parmesan for a sharper bite, or swap mozzarella with provolone for more melt and flavor.
- Spice it up: Add smoked paprika, Cajun seasoning, or extra red pepper flakes for heat.
- Herb options: Fresh basil, dill, or chives change the profile. Dill pairs especially well with shrimp and lemon.
- Protein changes: Try scallops or chunks of firm white fish.
If using chicken, pre-cook it since it needs more time than shrimp.
- Dairy-free approach: Use coconut cream instead of heavy cream and a dairy-free cheese alternative that melts well. Flavor with nutritional yeast for a cheesy note.
FAQ
Can I prep this ahead of time?
Yes. Assemble everything except the cheese up to 8 hours ahead, cover, and refrigerate.
When ready, top with cheese and bake. You may need an extra 2–3 minutes since it’s starting cold.
How do I prevent a watery bake?
Use thin zucchini slices, don’t overload the dish with cream, and bake uncovered so moisture can evaporate. Letting the dish rest for a few minutes after baking also helps the sauce settle.
What size shrimp works best?
Medium to large shrimp (31/40 or 21/25 count per pound) cook evenly without shrinking too much.
Smaller shrimp can overcook quickly, and extra-large may need a minute more in the oven.
Can I make it spicy?
Absolutely. Add more red pepper flakes, a pinch of cayenne, or a teaspoon of Cajun seasoning to the shrimp before baking.
Is this recipe gluten-free?
Yes, it uses no flour or breadcrumbs. Always check cheese labels to be sure there are no added starches if you’re sensitive.
What can I serve with it?
Cauliflower rice, a crisp green salad with olive oil and lemon, or roasted asparagus make great low-carb sides.
Keep it simple to let the bake shine.
Can I use frozen shrimp?
Yes, but thaw completely and pat dry very well. Excess moisture can water down the sauce and affect texture.
How many carbs are in a serving?
Exact macros vary by brands and portion size, but expect roughly 5–7 net carbs per serving when divided into four portions. For precision, run your exact ingredients through a nutrition calculator.
Do I need to peel the zucchini?
No.
The skin is tender and adds nutrients and color. Just wash well and slice.
Can I cook this on the stovetop?
You can. Sauté zucchini until just tender, add seasoned shrimp and cook until pink, then stir in the cream mixture and cheese to melt.
It won’t have the same bubbly baked top, but it’s fast and delicious.

This Keto Zucchini Shrimp Bake is the kind of meal you’ll make on repeat—simple steps, fresh flavors, and a creamy finish that feels more indulgent than it is.
