Keto Dinner

Light and Spicy Fish

I recall the first time I made this light and spicy fish—it was a revelation for weeknight keto dinners. The red snapper stays tender inside a foil packet, infused with tangy picante and lime. This dish comes together in minutes and delivers bold flavor without heavy carbs, making it a staple in my meal rotation.

Light and Spicy Fish

Ingredients

  • (6 ounce) fillets red snapper
  • /4 teaspoon garlic powder
  • salt and ground black pepper to taste
  • /4 cup picante sauce
  • /2 lime, juiced

Instructions

  1. Step 1

    First, I preheat my oven to 350°F (175°C) and tear off a piece of aluminum foil large enough to wrap both fillets. Place the foil on a baking sheet and give it a quick spritz of oil to prevent sticking. Lay the red snapper fillets on the foil and season them generously with garlic powder, salt, and freshly cracked black pepper. Next, spoon the picante sauce evenly over the fish, letting it pool on top. Squeeze the juice from half a lime over everything for that bright, citrusy kick. Now, bring the long sides of the foil together and fold them down, creasing tightly to seal. Then fold the ends to form a snug packet that traps steam and flavor. Slide the baking sheet into the oven and bake for 15 to 20 minutes. I always check at 15 minutes by opening a corner of the foil—if the fish flakes easily with a fork, it's ready. Serve the fillets straight from the packet with a spoonful of the tangy sauce on top.

Chef's Tip

I always add a few thin slices of jalapeño inside the packet before sealing for extra heat without extra carbs. The steam melts the spice into the fish beautifully.

Storage Tips

Store any leftover fish in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet with a splash of water to retain moisture, or enjoy cold over salad.

Variation Tips

Swap red snapper for cod, tilapia, or salmon for a different texture. Serve with cauliflower rice or a cucumber salad dressed in olive oil and vinegar. For a handheld meal, wrap the flaky fish in butter lettuce leaves. If you prefer a smoky note, use chipotle salsa and a pinch of cumin instead of picante sauce.
