What makes this recipe unique? It’s a masterclass in balance. You get protein from flaky fish and shrimp, fiber-rich pasta, earthy mushrooms, and a creamy filling that doesn’t tip the scale into “too much.” It’s decadent, yet light. Comforting, but not heavy. And bonus—it all comes together in one skillet for minimal cleanup.

How to make Stuffed Flounder and Pasta

  1. Mix shrimp, spinach, cheese, and spices for the filling.
  2. Spread filling on fish fillets, roll them up, and set aside.
  3. Cook bacon in a skillet; set aside and keep a bit of the grease.
  4. Sauté mushrooms and onions in the pan, then add garlic, herbs, and veggie stock.
  5. Place roll-ups into the skillet and bake until the fish is cooked through.
  6. Remove roll-ups, toss cooked pasta into the skillet with pasta water and bacon.
  7. Serve pasta topped with the roll-ups and crumbled bacon.

Tips & Tricks (aka Spaghetti Mastery)

  • Don’t overcook your pasta. Undercook by 2 minutes and finish in the sauce for perfect texture.
  • Slice mushrooms evenly so they caramelize instead of steaming.
  • Use a cast iron skillet to go from stovetop to oven easily.

Alternative Add-Ins

  • Swap flounder for sole, tilapia, or haddock—anything thin and rollable.
  • Add sun-dried tomatoes or kale to the filling for a veggie boost.
  • Try whole-grain or chickpea pasta if you’re looking to lower the carb load.

This dish checks all the boxes: flavor-packed, healthy-ish, simple enough for Tuesday but elegant enough for guests. Moderation isn’t deprivation—it’s just smart cooking. And these roll-ups? Smart, satisfying, and a little bit fancy.

FAQ for Stuffed Flounder and Pasta

Can I prep this ahead of time?

Not recommended. Filling the flounder in advance may toughen the texture, and reheated fish dries out easily

Can I use a different type of fish?

Yes! Tilapia, sole, or haddock work well as long as they’re thin and boneless.

How long do leftovers last?

2–3 days in the fridge. Just know reheating may dry out the fish slightly, so reheat gently.
