Makeover Spinach Tuna Casserole: A Comfort Food Classic, Reimagined

My grandmother, Nana Elsie, was the undisputed queen of casseroles. Every family gathering featured at least one bubbling dish, its surface a mosaic of golden-brown cheese and crispy breadcrumbs. While her creations were undoubtedly delicious, they were also… well, hearty. Let’s just say a single serving could keep you full for a week! This Makeover Spinach Tuna Casserole is my attempt to recapture the comforting essence of Nana Elsie’s cooking, but with a slightly lighter touch, perfect for a weeknight dinner that won’t leave you feeling sluggish.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 40 minutes
Total Time: 1 hour
Servings: 8
Dietary Type: Pescatarian

Ingredients

5 cups uncooked egg noodles
1 cup reduced-fat sour cream
1/2 cup fat-free mayonnaise
2-3 teaspoons lemon juice
2 tablespoons butter
1/4 cup all-purpose flour
2 cups nonfat milk
1/3 cup shredded parmesan cheese, divided (plus 2 tablespoons for topping)
1/2 cup sliced white button mushrooms
1 (10 ounce) package frozen chopped spinach, thawed and squeezed dry
1 (6 ounce) package reduced-sodium chicken flavor stuffing mix
1/3 cup seasoned bread crumbs
2 (6 ounce) cans light chunk tuna in water, drained and flaked
Hot sauce (optional)

Equipment Needed

Large pot
Small bowl
Large saucepan or Dutch oven
13″x9″ baking dish

Instructions

Begin by cooking the egg noodles according to the package directions. Ensure you cook them al dente, as they will continue to cook in the oven. Drain well once cooked.
While the noodles are cooking, prepare the sour cream mixture. In a small bowl, combine the reduced-fat sour cream, fat-free mayonnaise, and lemon juice. Mix well and set aside. The lemon juice adds a bright tang that cuts through the richness of the casserole.
Next, prepare the cheese sauce. In a large saucepan or Dutch oven, melt the butter over medium heat.
Stir in the flour until blended and smooth. This creates a roux, which is the base for the sauce.
Gradually stir in the nonfat milk, whisking constantly to prevent lumps from forming.
Bring the mixture to a boil, still stirring. Then, reduce the heat and cook and stir for 2 minutes, or until the sauce has thickened. This ensures the sauce is smooth and coats the noodles and other ingredients evenly.
Reduce the heat to low; stir in 1/3 cup of the shredded parmesan cheese until it is completely melted and incorporated into the sauce. This adds a nutty, savory flavor.
Remove the saucepan from the heat and stir in the sour cream mixture prepared earlier. If you enjoy a touch of heat, add a few dashes of hot sauce at this stage.
Now it’s time to add the main ingredients. Stir in the spinach (make sure it’s thoroughly squeezed dry to avoid a watery casserole), stuffing mix, bread crumbs, mushrooms, and tuna. Mix everything well until all ingredients are evenly distributed in the sauce.
Drain the cooked egg noodles and place them in a 13″x9″ baking dish that has been coated with nonstick cooking spray. This prevents the casserole from sticking to the bottom of the dish.
Top the noodles with the tuna mixture, spreading it evenly over the noodles.
Sprinkle the remaining 2 tablespoons of Parmesan cheese over the top of the casserole. This will create a golden-brown, crispy crust.
Cover the baking dish with foil and bake at 350°F (175°C) for 35 minutes. Covering the dish helps to ensure that the casserole is heated through without drying out.
Uncover the dish and bake for an additional 5-10 minutes, or until the top is lightly browned and the casserole is heated through. Keep a close eye on it to prevent burning.

Expert Tips & Tricks

Squeeze the spinach well! This is the most important step to prevent a watery casserole. Use your hands or a clean kitchen towel to remove as much moisture as possible.
Toast the breadcrumbs: For extra flavor and texture, lightly toast the seasoned breadcrumbs in a dry skillet before adding them to the casserole.
Adjust the seasoning: Taste the tuna mixture before adding it to the noodles and adjust the seasoning as needed. You may want to add a pinch of salt, pepper, or garlic powder.
Make it ahead: Assemble the casserole ahead of time and store it in the refrigerator, covered, for up to 24 hours. Add an extra 10-15 minutes to the baking time if baking from cold.
Swap the Tuna: Canned salmon or shredded cooked chicken also work beautifully in this casserole.

Serving & Storage Suggestions

Serve the Makeover Spinach Tuna Casserole hot, straight from the oven. A simple green salad or steamed vegetables makes a perfect accompaniment.

Leftovers can be stored in the refrigerator in an airtight container for up to 3 days. To reheat, microwave individual portions or bake the entire casserole in a preheated oven at 350°F (175°C) until heated through. The casserole can also be frozen for up to 2 months. Thaw it completely in the refrigerator before reheating.
