Difficulty level
Easy – perfect for weeknight dinners or meal prepping
Ingredients
- 12 oz whole grain or chickpea pasta (penne or shells work well)
- 2 cans (5 oz each) sustainably sourced tuna in water, drained and flaked
- 1 tablespoon olive oil or avocado oil
- 1 medium yellow onion, finely chopped
- 3 cloves garlic, minced
- 1 cup cremini mushrooms, sliced thin
- 2 cups fresh spinach, roughly chopped
- 1 cup reduced-fat milk (or unsweetened almond milk for dairy-free)
- 2 tablespoons whole wheat flour or chickpea flour
- 1/2 cup low-sodium vegetable or chicken broth
- 1 cup grated sharp white cheddar cheese, divided
- 1/2 cup plain Greek yogurt
- 1 teaspoon Dijon mustard
- Salt and freshly cracked black pepper, to taste
- 1/4 teaspoon smoked paprika
- 1/4 cup whole wheat breadcrumbs or gluten-free breadcrumbs
- Fresh parsley, chopped, for garnish
step-by-Step Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.
- Cook the pasta according to package instructions until al dente. Drain and set aside.
- In a large skillet, heat olive oil over medium heat. Add the chopped onion and sauté until translucent, about 4 minutes.
- Add garlic and mushrooms, sauté for another 5 minutes until mushrooms release their juices and are golden brown. Stir frequently to avoid sticking.
- Sprinkle the flour over the vegetables and stir well, cooking for 1 minute to remove the raw flour taste.
- Slowly whisk in milk and broth, stirring constantly until the mixture thickens-about 3-4 minutes. This creates a creamy, velvety base without heavy cream.
- Add dijon mustard,smoked paprika,salt,and pepper. Taste and adjust seasonings as needed.
- Remove from heat and stir in Greek yogurt for tangy creaminess. Fold in the cooked pasta, flaked tuna, fresh spinach, and half of the cheddar cheese. Mix gently until combined.
- Transfer the mixture to the prepared casserole dish. Sprinkle the remaining cheddar and breadcrumbs evenly over the top to create a golden crust.
- Bake uncovered for 20 minutes until bubbly and golden on top. Let rest 5 minutes before serving.
Chef’s Notes: Tips for Success
- For an extra veggie boost, add finely chopped zucchini or diced bell peppers along with the mushrooms.
- Swap whole grain pasta for lentil or chickpea pasta for added protein and fiber.
- If using canned tuna packed in oil, reduce or omit additional oil to keep the casserole light.
- Make it ahead: Prepare the base mixture and assemble in a casserole dish, refrigerate overnight, then bake fresh the next day.
- Craving crunch? Toast the breadcrumbs with a teaspoon of olive oil before sprinkling for an even crispier topping.
- For dairy-free versions, substitute Greek yogurt with coconut cream yogurt and use vegan cheese.
