Some weeknights call for a dinner that comes together fast and still feels like something you'd order out. This keto garlic shrimp with broccoli is exactly that. Juicy shrimp get seared until just pink, broccoli stays crisp-tender, and everything is finished in a garlicky butter sauce with a splash of lemon. It's ready in about 25 minutes, uses one skillet, and fits neatly into a low-carb or keto plan without tasting like "diet food."
I like this recipe because it doesn't ask much of you. There's no marinating, no fussy sauce reduction, and no obscure ingredients. It's the kind of dinner you can pull off after a long day, and it still looks like you tried.

Ingredients You'll Need
Here's what goes into this dish, along with a few notes on substitutions.
- Shrimp (1 lb, peeled and deveined): Large or extra large shrimp work best here since they hold up to the quick sear. Fresh or thawed frozen shrimp both work fine; just pat them dry first so they brown instead of steam.
- Broccoli florets (4 cups): Fresh broccoli gives the best texture, but frozen florets work too if you thaw and drain them well. Cauliflower is a solid swap if broccoli isn't your thing.
- Butter (4 tablespoons, divided): Butter is what gives this dish its rich, garlicky flavor. Ghee is a good dairy-adjacent option if you want that same richness.
- Olive oil (1 tablespoon): Helps keep the butter from burning while the shrimp sears.
- Garlic (5 cloves, minced): This dish is called garlic shrimp for a reason, so don't be shy with it. Jarred minced garlic works in a pinch.
- Red pepper flakes (0.5 teaspoon, optional): Adds a gentle background heat. Leave it out if you're cooking for spice-sensitive eaters.
- Lemon juice (2 tablespoons): Brightens the whole dish and balances the richness of the butter.
- Chicken broth (0.25 cup): Loosens the sauce just enough to coat everything without making it greasy. Vegetable broth works if that's what you have.
- Parmesan cheese (0.25 cup, grated, optional): Melts into the sauce for extra savoriness. Skip it if you want the dish dairy-light or need it dairy-free.
- Fresh parsley (2 tablespoons, chopped): For color and a fresh finish.
- Salt and pepper to taste.
Step-by-Step Instructions
1. Cook the broccoli. Bring a pot of salted water to a boil, or use a steamer basket. Cook the broccoli florets for 3 to 4 minutes, just until they turn bright green and are crisp-tender. Drain and set aside. This step keeps the broccoli from turning mushy once it goes back into the skillet later.
2. Season and sear the shrimp. Pat the shrimp dry with paper towels and season with salt and pepper. Heat 2 tablespoons of butter and the olive oil in a large skillet over medium-high heat. Once the butter is foaming, add the shrimp in a single layer. Sear for about 2 minutes per side, until they turn pink and opaque. Remove the shrimp to a plate; they'll finish cooking in the sauce later, so it's fine if they're not fully done yet.
3. Build the garlic butter sauce. Lower the heat to medium and add the remaining 2 tablespoons of butter to the same skillet. Add the minced garlic and red pepper flakes, and stir for about 30 seconds, just until the garlic turns fragrant. Don't let it brown or it will taste bitter.
4. Add the broth and lemon. Pour in the chicken broth and lemon juice, scraping up any browned bits from the bottom of the pan. Let it simmer for 1 to 2 minutes so the flavors come together, and the sauce reduces slightly.
5. Bring everything back together. Return the shrimp and broccoli to the skillet. Toss gently to coat everything in the garlic butter sauce and warm it through, about 2 minutes. If you're using parmesan, stir it in now so it melts into the sauce.
6. Finish and serve. Sprinkle with fresh parsley, taste, and adjust the salt and pepper if needed. Serve immediately while the shrimp is still tender and the sauce is glossy.
Tips for the Best Results
Getting this recipe right comes down to a handful of small details rather than any complicated technique.
Don't overcrowd the pan. If your skillet is small, sear the shrimp in two batches. Crowding the pan drops the temperature and causes the shrimp to steam instead of brown, which means you lose that slightly caramelized edge.
Watch the shrimp closely. Shrimp cook fast, usually in under 4 minutes total, and they go from tender to rubbery quickly. Pull them the moment they turn pink and curl into a loose C shape. A tight, tense curl usually means they've gone slightly past done.
Cut the broccoli evenly. Uniform, bite-sized florets cook at the same rate, so you won't end up with some pieces mushy and others still raw in the center.
Dry the shrimp before cooking. Excess moisture is the enemy of a good sear. A quick pat with a paper towel makes a real difference in how well the shrimp browns.
Taste before you salt heavily. Broth and parmesan both bring their own saltiness, so it's easier to add more at the end than to fix an oversalted sauce.
A common mistake to avoid: searing the shrimp fully in step 2 instead of pulling them slightly underdone. It's tempting to cook them all the way through right away, but shrimp keep cooking once they hit the hot sauce in step 5. If they're already fully cooked when they go back in, they'll almost certainly overcook and turn tough by the time you serve.
Serving Suggestions
This dish is satisfying enough to eat on its own, but it also pairs well with cauliflower rice, a simple green salad, or zucchini noodles if you want to stretch it into a bigger meal. A wedge of lemon on the side never hurts either.
Storage and Reheating
Let leftovers cool to room temperature, then store them in an airtight container in the refrigerator for up to 3 days. Shrimp doesn't freeze particularly well once it's been cooked in a sauce, since the texture tends to turn rubbery after thawing, so this recipe is best enjoyed fresh or refrigerated rather than frozen.
To reheat, warm the shrimp and broccoli gently in a skillet over medium-low heat for 2 to 3 minutes, just until heated through. Microwaving works too in 30-second bursts, but keep the power on medium so the shrimp doesn't overcook and turn tough. Add a small splash of broth or water if the sauce has thickened too much in the fridge.
Frequently Asked Questions
Can I use frozen shrimp? Yes. Thaw the shrimp fully in the refrigerator or under cold running water, then pat them very dry before seasoning. Excess water will prevent a good sear.
Is this recipe dairy free? It can be. Swap the butter for a dairy-free alternative or extra olive oil, and skip the parmesan. The dish will still be flavorful thanks to the garlic and lemon.
How many carbs are in keto garlic shrimp with broccoli? Each serving has around 6 grams of total carbs and about 4 grams of net carbs, which fits comfortably into most keto meal plans.
Can I add other vegetables? Definitely. Asparagus, green beans, or bell peppers all work well in place of or alongside the broccoli. Just adjust the cooking time so they end up tender rather than raw or mushy.
Why is my shrimp rubbery? Rubbery shrimp almost always means it was overcooked. Shrimp needs very little time in the pan, so pull it as soon as it turns pink and opaque, then let it finish warming through in the sauce rather than cooking it fully twice.
Can I make this ahead of time? This dish is best made fresh since shrimp toughens with reheating, but you can prep the broccoli and mince the garlic a day ahead to speed up cooking time.
