10 Keto Seafood Recipes: Low-Carb Fish Ideas

10 Keto Seafood Recipes: Low-Carb Fish Ideas

Seafood is one of the most underused proteins on keto, and I don’t know why. I’ve been eating this way for years and I still rotate through fish and shrimp constantly, not because I feel like I should, but because it’s some of the most satisfying food I make. There’s no hidden sugar, no weird fillers. It’s just protein and fat, exactly what you want.

The range here is bigger than people expect. You’ve got the Seared Salmon and Asparagus with Hollandaise, which looks like a restaurant plate but comes together in one pan and a blender. You’ve got a Keto Clam Chowder that holds up to any New England version I’ve had. And shrimp alone carries half this list in different directions: skillet with sausage, stuffed in poblanos, coconut-crusted, Cajun on cauliflower rice.

Seafood also pulls some nutritional weight that land proteins don’t. Salmon and fatty fish are among the best dietary sources of EPA and DHA, the omega-3 fatty acids tied to heart and brain health. And shrimp, often dismissed as too light, hits 35g of protein per serving in one of these recipes.

If fish hasn’t been a regular part of your keto rotation, this list is a good place to fix that.

1. Seared Salmon and Asparagus with Easy Hollandaise

Per serving: 721 cal | 63.6g fat | 3.5g net carbs | 30.3g protein

Seared salmon next to crispy asparagus spears, finished with hollandaise made in a blender: the whole thing happens in one pan and about 20 minutes. The salmon gets a golden-brown crust on the outside while staying just-set in the center. My girlfriend asked me to make this on a weeknight and I told her it was easier than it looked. She didn’t believe me until she watched me do it.

Salmon is one of the better dietary sources of EPA and DHA omega-3 fatty acids, which are linked to lower triglycerides and reduced inflammation, a benefit that comes up in multiple peer-reviewed reviews. At 721 calories and 63.6g fat with 30.3g protein per serving, it fits a high-fat keto macro profile without any adjustment.

2. Avocado Tuna Melt Bites

Per serving: 195 cal | 17.6g fat | 0.8g net carbs | 7.4g protein

Tuna and avocado packed into crispy bites: the outside browned and firm, the inside soft and creamy. These are easy to batch ahead and hold up in the fridge for a few days. I’ve made them Sunday and eaten them through Wednesday with no issues.

Each bite runs just 0.8g net carbs and 195 calories, which makes these the lowest-carb option on this list. The fat comes mostly from avocado, which brings oleic acid, the same monounsaturated fat found in olive oil, along with more potassium per gram than a banana.

3. Keto Shrimp and Sausage Skillet

Per serving: 450 cal | 34.2g fat | 6.0g net carbs | 29.0g protein

Shrimp and smoked sausage, seared in the same skillet with vegetables until everything picks up some color and the flavors merge. It’s one of those meals where the individual ingredients are simple but the combination reads as more than the sum of its parts. On the table in about 25 minutes. I’ve made this after long days when I didn’t want to think about cooking: it always delivers.

4. Keto Poke Bowls

Per serving: 499 cal | 38.2g fat | 6.6g net carbs | 28.2g protein

Poke bowls are usually built on rice, but swap in cauliflower rice and you’ve got the same concept: fresh-sliced fish, creamy toppings, and a seasoned base that soaks everything up. The first time I made these at home, I didn’t think cauliflower rice would hold its own against raw tuna and avocado. I was wrong: it absorbs the marinade well and the texture contrast works.

At 499 calories, 38.2g fat, and 6.6g net carbs per serving, these bowls hit higher fat macros than most fish dishes, mostly from avocado and sesame oil. If you’re tracking macros tightly, check out the keto macro calculator to see how a bowl like this fits your targets.

5. Keto Cilantro Lime Shrimp Stuffed Poblano Peppers

Per serving: 343 cal | 26.2g fat | 4.9g net carbs | 22.0g protein

Roasted poblano peppers stuffed with shrimp, garlicky cauliflower rice, and seasoned cream cheese. The peppers get some char before they’re filled, which gives them a slightly smoky edge that plays against the bright cilantro and lime in the filling. This one takes more steps than a skillet meal, but the result reads like something you’d order at a restaurant.

Poblanos are mild enough to not overpower the shrimp but still bring some capsaicin, which may support metabolism and reduce appetite. That’s the compound in chile peppers that creates heat. The shrimp adds 22g protein per serving at just 4.9g net carbs.

6. Keto Clam Chowder Recipe

Per serving: 535 cal | 42.0g fat | 7.4g net carbs | 29.5g protein

Clam chowder is one of those soups I thought I’d have to give up on keto because every recipe leans on potatoes and flour. This version replaces both: cauliflower does the starch work and heavy cream carries the fat, and the result is thick and silky in a way that doesn’t feel like a compromise. Clams bring a natural brininess that no substitute comes close to.

Clams are one of the better seafood sources of vitamin B12, which is tied to nerve health and red blood cell formation: most people don’t realize shellfish outperform even red meat per ounce on B12. At 535 calories and 42g fat per serving, this is a filling, high-fat bowl that works well as a complete meal.

7. Sesame Salmon Salad

Per serving: 440 cal | 33.8g fat | 4.2g net carbs | 27.7g protein

Cold sesame salmon salad, built with salmon and dressed in a soy-free Asian-style dressing. I tried this with store-bought sesame dressing the first time and the flavors were muddy: too sweet, not enough acid. Made the dressing from scratch the next time and it came together the way it was supposed to: bright with sesame, clean, not cloying. That’s the version on the site.

8. Low Carb Coconut Shrimp

Per serving: 363 cal | 20.0g fat | 7.6g net carbs | 35.5g protein

Coconut-crusted shrimp with real crunch. The coating doesn’t use traditional breadcrumbs: it holds together and crisps up without them, which I was skeptical about before I tried it.

Shrimp is one of the highest-protein seafoods by calorie count: this serving runs 35.5g protein with only 7.6g net carbs. The coconut coating brings medium-chain triglycerides from coconut, which your body can convert to ketones more readily than long-chain fats. See how this fits a weekly keto meal plan if you’re building a rotation.

9. Cajun Shrimp and Cauliflower Rice

Per serving: 487 cal | 33.6g fat | 8.4g net carbs | 36.1g protein

Cajun-spiced shrimp seared in bacon fat, served over cauliflower rice cooked until it resembles grits. The bacon fat is the move here: it adds a smokiness that straight butter or oil won’t give you.

10. Cilantro Lime Shrimp with Crispy Coconut Caulirice

Per serving: 360 cal | 24.5g fat | 10.7g net carbs | 23.5g protein

Zesty cilantro-lime shrimp over coconut cauliflower rice that gets pan-fried until the edges are golden and slightly crispy. The contrast between the bright shrimp and the toasted, slightly sweet cauliflower base is what makes this work.

Shrimp is naturally very low-carb and provides selenium, which supports thyroid function and acts as an antioxidant in the body. At 10.7g net carbs, this is the highest-carb entry on the list, but with 23.5g protein and 24.5g fat, the macro balance holds. The coconut milk in the caulirice adds MCTs that digest differently than most dietary fats, helping support ketone production.

Frequently Asked Questions

Is seafood good for keto?

Most seafood is a natural fit for keto: fish and shellfish are high in protein, low in carbs, and bring fats that most land proteins don’t, especially omega-3s from fatty fish like salmon. Breaded or battered versions are the ones to watch, but plain seafood cooked in butter or oil fits keto without modification. Check the keto food list for a breakdown of what seafood fits where.

How much omega-3 do you get from keto fish recipes?

It depends on the fish. Fatty fish like salmon and mackerel provide EPA and DHA directly, the forms of omega-3 your body uses for inflammation regulation and brain health. A single 4oz serving of salmon can deliver 1.5-2g of combined EPA and DHA, which meets or exceeds most daily intake targets. Shrimp and clams have less omega-3 by weight but still contribute meaningfully to weekly intake. For more on how fat intake works in keto, see the full keto diet guide.

Can I eat shrimp every day on keto?

Shrimp is low in carbs and high in protein, so from a macro standpoint, yes. The main consideration is cholesterol: shrimp is relatively high in dietary cholesterol, though current nutrition evidence suggests this matters less than once thought for most people. Rotating between shrimp, fatty fish, and other proteins is a reasonable approach. The keto macro calculator can help you see how shrimp fits your daily protein targets.

What can I use instead of potatoes in keto clam chowder?

Cauliflower is the standard swap: it gets soft in the broth and absorbs flavor well, mimicking the texture of potato chunks without the carb load. Some recipes also use turnip or celeriac, which hold up a bit firmer. The keto clam chowder recipe on ruled.me uses cauliflower and keeps the broth thick with heavy cream instead of flour, which keeps the net carbs under 8g per serving.

Are these keto seafood recipes beginner-friendly?

Most of them are. The shrimp skillet, Cajun shrimp and cauliflower rice, and the tuna avocado bites are all straightforward: minimal technique, common ingredients, hard to get wrong. The hollandaise in the salmon recipe sounds fussy but the blender method takes most of the difficulty out. If you’re new to keto cooking, the keto beginners guide covers the basics before you dive into specific recipes.


Putting It All Together: Keto Seafood Recipes

If you’re only going to make one thing from this list, start with the seared salmon and hollandaise: it’s the most impressive for the effort it requires. From there, the shrimp skillet and Cajun shrimp and cauliflower rice are reliable weeknight options that I’ve made more times than I can count. Seafood doesn’t need to be a once-in-a-while thing on keto. It fits the macros better than most proteins and the omega-3s you pick up from regular fish consumption are worth something.
