Tuna Noodle Casserole from Scratch

Tuna Noodle Casserole from Scratch 

Recently my tastebuds traveled back to my mom’s classic tuna casserole of the 70s and 80s. My flashback made me want to replicate and enjoy this comforting dish immediately.

My mother always cooked everything from scratch, so her tuna noodle casserole recipe was no exception.

Instead of canned cream of mushroom soup, this recipes uses a simple sauce of butter, milk, seasonings, and mushrooms. It’s thickened with cornstarch so the sauce is naturally gluten free.

Tuna Noodle Casserole from scratch can be made with traditional egg noodles, or swap them out for gluten free penne.

Is Tuna Casserole Healthy?

This casserole has 500 calories per serving using light mayonnaise, sour cream, and 2% milk. However, there are ways to make it this Tuna Noodle Casserole recipe even healthier.

• Substitute 1% or skim milk. 
• Use fat free mayonnaise and sour cream
• Omit the potato chip topping, halve the amount, or substitute breadcrumbs.

This Tuna Noodle Casserole Recipe is Gluten Free? 

Yes, you can still enjoy classic tuna noodle casserole gluten free! The sauce contains no condensed cream of mushroom soup and is thickened with cornstarch. 

Unfortunately gluten free egg noodles aren’t readily available, but penne pasta is a perfect substitute. The copycat sauce, cheddar cheese, peas, flaky tuna, and potato chip topping mimics that throwback taste identically so all can enjoy! 

What Do You Eat With Tuna Casserole?

Since this casserole recipe is pretty filling, a lighter, simpler side dish pairs great with it! A fresh fruit salad, steamed veggies, or green salad makes a great accompaniment. 

• Steamed veggies, such as corn, broccoli, or green beans.
• Roasted veggies, such as roasted brussels sprouts, bacon roasted green beans & potatoes, or butternut squash
• Applesauce  
• Green salad, such as Apple Pecan Salad
• Another throwback dish – Jello Salad!

Can You Freeze Tuna Noodle Casserole?

Yes, you can freeze tuna noodle casserole, which can be done before baking or after. 

How to freeze UNBAKED tuna noodle casserole: 

1. Assemble casserole, cover tightly, and freeze for up to 3 months.
2. When ready to serve, thaw completely in the refrigerator overnight.
3. Bake according to directions, adding 10-15 minutes to heat thoroughly.

How to freeze BAKED tuna noodle casserole:

1. Portion baked casserole into serving sizes and freeze up to 3 months. (Reheating an entire baked tuna casserole will make it dry out.)
2. Thaw serving in the refrigerator.
3. Microwave at 50% power until almost heated through, stirring occasionally. Finish heating at full power to warm completely.
4. To make topping crispy again, place serving in an oven-proof container, sprinkle cheese on top, and broil for 1-2 minutes. 

How To Make Homemade Tuna Noodle Casserole 

1. Preheat oven to 350°F and grease a 9X13 baking dish.
2. Sauté the fresh mushrooms and onions in butter until vegetables are soft. Make sure you’re using a big enough pot to add in 2 cups of milk. 
3. Add the milk and seasonings to the pot. Bring to a boil and then add cornstarch mixed with chicken broth. Cook until thickened.
4. Gently mix all the casserole ingredients together in a large bowl.
5. Pour tuna mixture into prepared dish, top with potato chips, and bake for 30-40 minutes. 

Toppings for the Best Tuna Noodle Casserole

I like the potato chip topping because it’s reminiscent of the recipe my mom made. (Plus, what kid is going to complain about potato chips on their dinner?!) Want to try something different? Check out these alternative toppings!

• Sprinkle on sharp cheddar, parmesan cheese, swiss, or colby to make an extra cheesy tuna noodle casserole. 
• In a small bowl mix together 1/2 cup bread crumbs or panko with 1 tablespoon melted butter. 
• Crushed Ritz crackers
• Crispy fried onions (it’s not just for green bean casserole!)
• Make a combination! Add 1/2 cup grated cheese to bread crumbs, crackers, or fried onions

Tips for Making Tuna Noodle Casserole From Scratch

• Be careful to not overcook the pasta! Anytime you bake a dish with gluten free pasta, do not boil the noodles long. Boiling for half the time called for al dente ensures the pasta doesn’t become mushy during baking.
• Rinsing the gluten free noodles in cold water after boiling helps to stop the cooking. Otherwise they will steam and cook more while waiting to be mixed with other ingredients.
• Don’t forget to cook hard boiled eggs ahead of time. The easiest and foolproof way to boil eggs is with an egg cooker. If you aren’t a hardboiled egg fan, you can leave them out. 
• If you aren’t gluten free, this recipe will work with regular egg noodles too. Use a 12 ounce package and boil them to almost cooked through before mixing with the sauce and other casserole ingredients.
• Try squeezing some fresh lemon juice on right before serving!

How Long is Tuna Noodle Casserole Good For?

Tuna Noodle Casserole will keep for 2-3 days refrigerated in an airtight container. 

HOW TO REHEAT:

Take out a serving size and place on a microwave safe dish. Heat at 50% power for 2 minutes. Mix gently to not disturb topping and finish heating at full power for 1-2 minutes, or until heated through. If you like to recreate the crispy topping, add a few more crushed potato chips or crackers on top before serving.
