Prep and Cook Time
Preparation: 15 minutes | Cooking: 30 minutes | Total: 45 minutes
Yield
Serves 6 generous portions
Difficulty Level
Easy - perfect for weeknight dinners or meal prep enthusiasts
Ingredients
- 8 ounces whole-wheat elbow macaroni (or gluten-free pasta for an option)
- 2 cans (5 oz each) tuna in water, drained and flaked
- 1 cup plain Greek yogurt (as a creamy, protein-rich base)
- 1/2 cup low-fat milk
- 1 tablespoon olive oil
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 cup mushrooms, sliced
- 1 cup fresh spinach, roughly chopped
- 1 teaspoon dried thyme
- 1 teaspoon Dijon mustard
- 1/2 cup grated Parmesan cheese
- 1/2 cup whole-wheat panko breadcrumbs
- 1/4 cup slivered almonds (toasted)
- Salt and freshly ground black pepper, to taste
- Fresh parsley for garnish
Instructions
- Cook the pasta: Bring a large pot of salted water to a boil. Add the whole-wheat elbow macaroni and cook according to package instructions until al dente. Drain and set aside.
- Sauté aromatics: in a large skillet, heat olive oil over medium heat. Add chopped onion and sauté until translucent, about 5 minutes. Add minced garlic and cook for another 1 minute, stirring frequently to prevent burning.
- Cook mushrooms and spinach: Add sliced mushrooms to the skillet and sauté until golden brown, about 6 minutes. Toss in fresh spinach and cook until just wilted, roughly 2 minutes.
- Prepare the sauce: Lower the heat. Stir in Greek yogurt, low-fat milk, Dijon mustard, dried thyme, salt, and pepper. Mix thoroughly until the sauce is smooth and slightly thickened. Warm gently for 3-4 minutes, stirring occasionally.
- Combine tuna and pasta: Add the drained and flaked tuna along with cooked pasta into the skillet.Fold everything carefully to coat pasta without breaking up the tuna too much.
- Transfer to casserole dish: Preheat oven to 350°F (175°C). Pour the tuna and pasta mixture into a greased 9×13 inch baking dish. Sprinkle grated Parmesan evenly over the top.
- Prepare topping: in a small bowl, mix whole-wheat panko breadcrumbs with toasted slivered almonds for that irresistible crunch. Sprinkle this mixture evenly over the casserole.
- Bake to perfection: Bake uncovered for 20-25 minutes or until the top is golden brown and bubbly around the edges. Remove from oven and let rest for 5 minutes.
- Garnish and serve: Sprinkle with freshly chopped parsley before serving for a pop of color and fresh aroma.
Tips for Success
- Balance creaminess and texture: Using Greek yogurt instead of heavy cream adds protein and tanginess while keeping the casserole lighter.
- Vegetable variations: Feel free to add peas, bell peppers, or broccoli florets for an extra nutrient boost.
- Make-ahead magic: Assemble the casserole up to step 7, cover tightly, and refrigerate for up to 24 hours. Bake fresh when ready to serve.
- Crispy topping tip: Toast the slivered almonds in a dry pan until golden brown-this unlocks a splendid nuttiness that elevates the dish.
- Gluten-free option: Swap whole-wheat pasta and panko with certified gluten-free versions without sacrificing flavor or texture.
Serving Suggestions
Present your nutritious tuna casserole steaming hot, complemented by a bright side salad of mixed greens and cherry tomatoes dressed lightly with lemon vinaigrette. Garnish each serving with a sprinkle of fresh parsley or chives for an herbal aroma. For added zest, offer a wedge of lemon on the side to squeeze over the casserole’s creamy layers. This dish pairs beautifully with crisp white wine or a refreshing sparkling water infused with cucumber and mint.
