Another classic mistake is skipping the foil during the first bake. I thought, “It’s a casserole, it’ll be fine!” Without that foil tent, the top cheese browns too quickly, the exposed noodles on top get hard, and the ones underneath don’t cook through. You need that moist, steamy environment. And when you add the fried onions, only bake until they are golden, not deeply brown. They continue to crisp up as the dish cools, and if you overdo it, they can burn and taste bitter.
Serving Suggestions
I love serving this casserole straight from the baking dish at the table—it feels so homey and inviting. For a complete, balanced meal, I always pair it with something fresh and crisp to cut through the richness. A simple green salad with a bright vinaigrette is my absolute go-to. The tangy dressing is the perfect counterpoint to each creamy, savory bite. It just lightens the whole plate up.
On colder nights, I’ll serve it with some roasted garlic green beans or honey-glazed carrots on the side. The sweetness of the carrots is a fantastic complement. And if I’m being completely honest, a dash of hot sauce or a side of spicy pickles for those who want a kick is always a hit at my table. It’s such a versatile centerpiece that almost any veggie side feels right alongside it.
Variations & Customizations
This recipe is a wonderful canvas! One of my favorite twists is a “Southwest” version. I use a can of Rotel diced tomatoes & green chiles (drained) instead of peas, add a teaspoon of cumin and chili powder to the beef, and use a Monterey Jack and cheddar cheese blend. It’s fantastic topped with crushed tortilla chips instead of fried onions. My family requests this version all the time.
For a lighter take, I’ve successfully used ground turkey and swapped the cream of mushroom for cream of chicken. You can also add in different veggies based on what you have. Diced bell peppers sautéed with the onion, thawed chopped spinach (squeezed very dry), or even some sliced mushrooms are all great additions. The core method stays the same, so feel free to get creative and make it your own!
How to Store, Freeze & Reheat
Leftovers keep beautifully! Once completely cooled, I store them in an airtight container in the fridge for up to 4 days. To reheat, I’ve found the microwave can make the noodles a bit rubbery. My best method is to reheat individual portions in a covered oven-safe dish at 325°F until warmed through, about 15-20 minutes. For a larger portion, I’ll cover the baking dish with foil and reheat at 350°F for 25-30 minutes. This keeps the texture perfect.
Yes, you can freeze this casserole! Assemble it completely in a freezer-safe dish, but do not add the fried onion topping. Cover tightly with plastic wrap and then foil. Freeze for up to 2 months. To cook, thaw it overnight in the fridge, then let it sit on the counter for 30 minutes before baking. Add the fried onions during the last 10-15 minutes of baking as directed. You may need to add 5-10 extra minutes to the covered baking time if it’s still chilly in the center.
FAQ Section
Can I make this casserole ahead of time?
Absolutely, and I do it often for busy weeks! You can assemble the entire casserole (minus the fried onion topping) up to 24 hours in advance. Cover it tightly and store it in the fridge. When you’re ready to bake, let it sit on the counter while the oven preheats (about 20 minutes), then bake as directed, adding a few extra minutes to the covered bake time if needed. Add the onions at the usual time.
My casserole came out a bit dry. What happened?
This usually means the heat was too high or it baked a little too long. All ovens vary! I recommend using an oven thermometer to check your oven’s true temperature. Also, make sure you’re using a standard 9×13 dish—a larger dish will spread the mixture thinner and cause it to dry out. Finally, don’t over-measure your noodles; a heaping cup can soak up too much liquid.
Can I use a different canned soup?
You can, but the flavor profile will change. Cream of chicken or cream of celery soup work very well. I would avoid cream of broccoli or cheese soups, as they can make the final dish taste a bit off or overly processed. The mushroom soup provides a subtle, savory umami that I think is perfect, but cream of chicken is a very close and delicious second in my book.
