Crab-Stuffed Flounder – paleo recipe

Serves: 4

Ingredients

  • 1 tbsp (15 ml) coconut oil, divided

  • 3 scallions (white parts chopped fine, green parts sliced thin on bias)

  • 1 celery rib, minced

  • 0.5 red bell pepper, chopped fine

  • 1 garlic clove, minced

  • 0.75 tsp (3.8 ml) Cajun seasoning

  • 3 oz (approx 85g) Coconut Milk Cheddar Cheese, cut into small pieces

  • 12 oz (approx 340g) lump crabmeat, picked over for shells

  • 2 cups (480 ml) fresh spinach, stemmed

  • Sea salt and pepper to taste

  • 8 skinless flounder fillets (3 oz / 85g each), 0.25- to 0.5-inch thick

  • 0.25 cup (60 ml) White Sandwich Breadcrumbs, toasted

Preparation

  1. Adjust the oven rack to the middle position and preheat the oven to 475°F (245°C).

  2. Heat 2 tsp (10 ml) of the coconut oil in a 10-inch nonstick skillet over medium heat until shimmering. Add the scallion whites, celery, and bell pepper. Cook until softened, about 5 minutes.

  3. Stir in the garlic and 0.75 tsp (3.8 ml) Cajun seasoning and cook until fragrant, about 30 seconds.

  4. Remove the skillet from the heat and stir in the 3 oz (85g) cheese until it is melted. Transfer this mixture to a large bowl.

  5. Gently stir the 12 oz (340g) crabmeat and 2 cups (480 ml) spinach into the bowl, being careful not to break up the lumps of crab. Season with sea salt and pepper to taste.

  6. Grease a 13x9-inch baking dish with coconut oil.

  7. Pat the flounder fillets dry with paper towels and season them with sea salt and pepper. Place the fillets, smooth side down, on a cutting board.

  8. Mound the filling in the center of each fillet. Fold the tail end over the filling, and then fold the thicker end over that.

  9. Lay the flounder seam-side down in the prepared baking dish.

  10. Toss the 0.25 cup (60 ml) breadcrumbs with the remaining 1 tsp (5 ml) of coconut oil, then sprinkle the breadcrumbs over the flounder.

  11. Bake until the filling is hot and the flounder flakes apart when gently prodded with a paring knife, about 20 minutes.

  12. Sprinkle with the reserved scallion greens and serve immediately.

Crab-stuffed flounder is weeknight luxury at its best: sweet lump crab folded into a creamy, Cajun-spiced filling and wrapped in delicate white fish. The rolls bake in twenty minutes under a crisp, oil-toasted crumb lid. It looks like restaurant food and eats like a hug.

Pro Tips

  • Pick over the crabmeat for shell, then fold it in at the very end rather than stirring - lump crab breaks up easily, and you want those sweet, pearl-sized lumps to survive.
  • Fillets fold cleanly only when they are 1/4- to 1/2-inch thick. If yours are thicker, butterfly them open first, otherwise the roll cracks at the seam.
  • Tossing the breadcrumbs with the remaining coconut oil before sprinkling is what keeps the lid crunchy instead of soggy under the oven's 475°F heat.
  • Lay the rolls seam-side down in the dish - that single habit stops them from unfurling as the fish contracts in the oven.
  • Leftovers reheat gently at 325°F, covered with foil; crab turns rubbery if you blast it hot and fast.

Frequently Asked Questions

Can I assemble crab-stuffed flounder ahead of time?

Yes. Roll and fill the fillets up to a day ahead, keep them covered in the fridge, and add the buttered crumb topping just before baking. Give cold rolls an extra five minutes in the oven.

What fish can I stand in for flounder?

Any thin, mild white fillet works - sole, plaice, or thin-cut cod. Stay in that 1/4- to 1/2-inch range so the fold still holds.

Can I use canned crabmeat in the filling?

Well-drained canned lump crab is a fine substitute. Press out the excess moisture first, or the filling turns watery inside the roll.

How do I store leftover crab-stuffed flounder?

Cool the baked rolls completely and refrigerate them in a sealed container for up to two days. Rewarm at 325°F only until heated through.
