3. Add 1.5 pounds of boneless, skinless chicken pieces to the skillet and cook for 5-7 minutes, stirring occasionally, until they are lightly browned and no longer pink inside.
4. Tip: Don’t overcrowd the skillet to ensure the chicken gets a nice sear without steaming.

8. In a large mixing bowl, combine the cooked quinoa, sautéed vegetable mixture, shredded sharp cheddar cheese, whole milk, lightly beaten eggs, kosher salt, black pepper, and smoked paprika.
9. Mix everything together until well combined, ensuring the eggs are evenly distributed to help bind the casserole.
10. Transfer the mixture to the prepared baking dish and spread it out into an even layer.
11. Bake in the preheated oven for 25–30 minutes, until the top is golden brown and the center is set—a toothpick inserted should come out clean.
12. Let the casserole cool for 5–10 minutes before serving to allow it to firm up slightly.
13. Leftovers store beautifully in the fridge for up to 3 days, and you can reheat individual portions in the microwave for a quick meal.
14. Looking at the finished dish, you’ll love the creamy, cheesy texture with pops of tender broccoli and fluffy quinoa—it’s hearty without being overly rich. For a creative twist, try topping it with a sprinkle of crispy breadcrumbs or serving it alongside a simple green salad dressed with lemon vinaigrette to balance the flavors.

Tuna and Spinach Casserole

Tuna and Spinach Casserole
Now, if there’s one dish that’s saved me on more than one hectic weeknight, it’s this cozy tuna and spinach casserole. I first threw it together years ago when my pantry was nearly bare, and it’s been a comforting staple ever since—perfect for those evenings when you crave something hearty without a fuss.

Serving: 6 | Pre Time: 15 minutes | Cooking Time: 30 minutes

Ingredients

– 2 (5-ounce) cans of solid white albacore tuna in water, drained well
– 10 ounces of fresh baby spinach leaves, rinsed and patted dry
– 8 ounces of wide egg noodles
– 1 cup of shredded sharp cheddar cheese
– 1/2 cup of finely grated Parmesan cheese
– 1 cup of whole milk
– 1/2 cup of sour cream
– 1/4 cup of unsalted butter
– 1/4 cup of all-purpose flour
– 1 small yellow onion, finely diced
– 2 cloves of garlic, minced
– 1 teaspoon of dried dill weed
– 1/2 teaspoon of paprika
– 1/4 teaspoon of freshly ground black pepper
– 1/4 teaspoon of kosher salt

Instructions

1. Preheat your oven to 375°F and lightly grease a 9×13-inch baking dish with butter or cooking spray.
2. Bring a large pot of salted water to a rolling boil and cook the wide egg noodles according to package directions until al dente, about 8-10 minutes, then drain and set aside.
3. In a large skillet over medium heat, melt the unsalted butter until foamy, then add the finely diced yellow onion and cook for 5-7 minutes until softened and translucent.
4. Add the minced garlic to the skillet and sauté for 1 minute until fragrant, being careful not to let it burn.
5. Sprinkle the all-purpose flour over the onion and garlic mixture, stirring constantly for 2 minutes to form a smooth roux—this helps thicken the sauce without lumps.
6. Gradually whisk in the whole milk until fully incorporated, then bring to a gentle simmer and cook for 3-5 minutes until the sauce thickens slightly.
7. Remove the skillet from heat and stir in the sour cream, shredded sharp cheddar cheese, finely grated Parmesan cheese, dried dill weed, paprika, freshly ground black pepper, and kosher salt until the cheese melts and the sauce is creamy.
8. Gently fold in the drained solid white albacore tuna, fresh baby spinach leaves, and cooked wide egg noodles until everything is evenly coated with the sauce.
9. Transfer the mixture to the prepared baking dish, spreading it out evenly, and bake at 375°F for 25-30 minutes until the top is golden and bubbly.
10. Let the casserole rest for 5 minutes after baking to set—this makes it easier to serve without falling apart.
Just out of the oven, this casserole boasts a creamy, tender texture with pops of flaky tuna and wilted spinach, all wrapped in a cheesy, herb-infused sauce. I love serving it with a crisp green salad or crusty bread to soak up every last bit, and it reheats beautifully for leftovers the next day.
