The first time I made these low carb shrimp foil packets with zucchini, it was one of those sticky August evenings when turning on the stove felt like a personal betrayal. I wanted something that tasted like summer on a plate without the cleanup that makes me avoid cooking altogether. The grill was already hot from my husband’s burgers, and I thought—why not let the fire do all the work while I sip something cold on the porch?
My grandmother used to wrap fish in foil with lemon slices from her backyard tree, and we’d eat it straight from the packet, steam rising into the humid Georgia air. She never measured anything, just trusted her hands. When I opened my first batch of these packets and that garlicky, buttery steam hit my face, I was right back on her screened porch, swatting mosquitoes and feeling completely content.
This recipe has become my weeknight salvation—fifteen minutes of prep, zero pans to wash, and dinner that feels special without the effort. If you’re craving more hands-off seafood dinners, my low carb shrimp and sausage skillet delivers that same satisfaction with a completely different flavor profile.
What You Need to Make This Recipe
The magic here lives in a few carefully chosen players. I use jumbo shrimp because they hold their texture through the high heat without turning rubbery—smaller shrimp surrender too quickly and you lose that satisfying bite. Fresh zucchini is non-negotiable; it releases just enough moisture to create a gentle steam inside the packet without drowning everything in liquid. And please, don’t skimp on the butter—it’s what carries the garlic and herbs into every crevice of the shrimp. The foil does the heavy lifting, but these ingredients make low carb shrimp foil packets with zucchini worth repeating. For another grilled seafood adventure, try my grilled swordfish—it taught me everything I know about cooking fish over open flame.
How to Make Low Carb Shrimp Foil Packets With Zucchini
I start by slicing zucchini into thin half-moons—they cook faster this way and nestle around the shrimp like little green spoons. The shrimp go in raw, tossed with melted butter, minced garlic that I’ve smashed rather than chopped (more flavor, less burning), and whatever herbs are threatening to wilt in my crisper drawer. I fold the foil into tight little envelopes, crimping the edges like I’m sealing a letter to someone I actually like.
On the grill, the packets puff up within minutes—that’s the steam building, the signal that something good is happening inside. I give them eight minutes, no peeking, then let them rest off-heat for two more. When you tear open that first packet, the smell is almost unfair: sweet shrimp, mellow garlic, butter that has browned slightly against the hot foil. The zucchini surrenders completely, soft and silky, having absorbed every bit of seasoned fat. If you’re into zucchini as a pasta replacement, my lemon garlic shrimp zucchini noodle recipe uses the same vegetable in a completely different way.
Pro Tips
Double-layer your foil on the bottom. I’ve had packets leak on the grill and watched precious butter drip into the flames—heartbreaking. Two layers gives you insurance without changing the cooking time.
Pat your shrimp aggressively dry before seasoning. Excess moisture dilutes the butter mixture and prevents that slight caramelization that makes the difference between good and unforgettable.
Cut zucchini uniformly thin. Thick slices stay crunchy while thin ones turn to mush—aim for quarter-inch and they’ll finish perfectly tender right when the shrimp are done.
My Secret Trick: I place a thin lemon slice directly on the grill grate underneath each packet, not inside it. The heat caramelizes the lemon’s sugars, and when I squeeze that smoky, concentrated juice over the finished dish, it tastes like I planned something far more sophisticated than foil packets.
How to Store Low Carb Shrimp Foil Packets With Zucchini
- Refrigerate in airtight containers for up to 2 days—foil packets transfer poorly, so move contents to glass or plastic before chilling
- Freeze only the raw prepared packets, not cooked—assemble and freeze flat for up to 1 month, then cook directly from frozen, adding 4-5 minutes
- Reheat gently in a 300°F oven covered with foil for 8-10 minutes, or in a skillet with a splash of water over medium-low heat—microwave turns shrimp rubbery
- Never leave at room temperature longer than 2 hours—seafood safety is not negotiable
Nutritional Benefits
These low carb shrimp foil packets with zucchini deliver serious protein without the carb load that weighs me down—roughly 25 grams per serving from the shrimp alone, with all nine essential amino acids present. The zucchini contributes meaningful potassium and vitamin C that actually survives the gentle steam cooking, plus enough fiber to keep this meal genuinely satisfying. I notice I don’t reach for snacks after eating this, which I can’t say about most quick dinners.
FAQs
Can I make these in the oven instead of on the grill?
Absolutely—bake at 425°F for 12-14 minutes on a sheet pan. You lose a whisper of smoky char but gain year-round accessibility. The packets puff and steam exactly the same way.
How do I know when the shrimp are fully cooked?
They turn opaque pink and curl into a loose C shape. Overcooked shrimp tighten into an O and turn rubbery—pull them when they still have slight translucency in the center; carryover heat finishes the job.
What other vegetables work in these packets?
Bell peppers, thin asparagus, and cherry tomatoes all succeed—just avoid watery vegetables like regular tomatoes or dense ones like carrots that won’t soften in time. Match your cuts to quick-cooking needs.
Can I prep these low carb shrimp foil packets with zucchini ahead of time?
Assemble raw packets up to 24 hours ahead and refrigerate—don’t add lemon juice until cooking or it will start curing the shrimp. Cooked leftovers degrade quickly, so plan to eat what you make.

Ingredients
Equipment
Method
- Preheat your oven to 425 degrees F. Tear four sheets of heavy duty aluminum foil, each about 12 inches long. Lay them flat on your counter.
- In a small bowl, whisk together the melted butter, minced garlic, lemon juice, lemon zest, red pepper flakes, oregano, and 1/4 teaspoon of the salt.
- Toss the zucchini slices with the remaining 1/2 teaspoon salt and black pepper. This helps draw out moisture so the packets don't get watery.
- Divide the zucchini evenly among the four foil sheets, arranging in a single layer in the center. Top each with about 6 ounces of shrimp. Drizzle the garlic butter sauce evenly over everything, making sure some garlic lands on each packet.
- Fold the long sides of the foil up and over the shrimp, then roll down to seal. Fold in the short ends and roll to create a tight packet. Leave a little air space inside for steam. Place packets on a large baking sheet.
- Bake for 12 to 15 minutes, until the shrimp are pink and opaque throughout and the zucchini is tender. Carefully open a packet to check - the shrimp should curl into a C shape, not a tight O (that means overcooked).
- Open the packets carefully - hot steam will escape. Sprinkle with fresh parsley and serve straight from the foil or transfer to plates. Add extra lemon wedges if you like.
