Not Your Mom's Tuna Noodle Casserole Recipe (No Canned Soup, High Fiber, High Protein) High Protein Recipes High Fiber Recipes Gluten-free Casseroles Dinner Seafood Pasta

This is not your typical tuna noodle casserole recipe. First of all, there’s no cream of mushroom soup in it. Second, it combines fresh vegetables with pantry staples to boost nutrition. Third, it’s got a seriously creamy, crispy and tangy flavor, thanks to two kinds of mustard and a whole lemon. Fourth, the topping adds a crave-able crunch factor. And finally, it’s gluten-free, high in protein and high in fiber.

Here is your shopping list for this elevated tuna casserole recipe: canned albacore tuna (read about the health benefits of tuna), canned sweet green peas, red bell pepper (check out the health benefits of red bell pepper), celery, gluten-free noodles (or whatever noodles you like), milk, fresh garlic, gluten-free flour (or all-purpose flour if you're not on a gluten-free diet), yellow mustard, Dijon mustard or honey mustard, lemons and mayonnaise. For the topping you'll need almond flour or breadcrumbs, Parmesan cheese and olive oil.

I intentionally didn’t pre-cook the fresh vegetables, so they wouldn’t get mushy. I prefer them crisp. But if you prefer softer veggies, you can sauté the celery and red pepper in a bit of olive oil until tender, before adding them to the casserole mixture.

This tasty tuna noodle casserole recipe is a complete high-protein dinner, but you could serve it for dinner with a side salad or separate vegetable, such as steamed broccoli, if you’d like.
