Sometimes, dinner needs to feel like a cozy blanket on a chilly evening. This tuna casserole no milk version hits that spot without any fuss. The creamy texture comes from broth and sour cream, which makes it rich without relying on milk. It’s one of those dishes that fills the kitchen with a homey aroma and invites everyone to gather around the table, even if the day was a little hectic or distracted — like when I forgot the timer and the edges got a bit crispier than planned, but honestly, that just added to the charm.
One evening, I threw this casserole together after a long day. The way the garlic and mushrooms sizzled in the pan made me pause for a moment — the smell was so comforting it almost made me forget the stack of emails waiting on my phone. I wasn’t exactly sure how the potato chip topping would turn out, but that crunch added a surprise that made everyone at the table smile. It’s a reminder that sometimes, a little imperfection in the kitchen leads to the best memories.

Ingredients
8 ounces egg noodles
1 tablespoon olive oil
1 medium onion, diced
2 cloves garlic, minced
1 cup sliced mushrooms
1 can (10.5 ounces) condensed cream of mushroom soup (dairy-free or regular if preferred)
1 cup chicken broth
1/2 cup sour cream
2 cans (5 ounces each) tuna in water, drained
1 cup frozen peas
1 cup shredded cheddar cheese
1/2 cup crushed potato chips
1/4 teaspoon black pepper
1/2 teaspoon dried thyme
Instructions
Preheat the oven to 350°F (175°C).
Cook the egg noodles according to package instructions until al dente. Drain and set aside.
Heat olive oil in a large skillet over medium heat. Add diced onion and cook for 3-4 minutes until translucent.
Add minced garlic and sliced mushrooms to the skillet. Cook for 5 minutes until mushrooms are tender.
In a large mixing bowl, combine the cooked onion, garlic, mushrooms, cream of mushroom soup, chicken broth, sour cream, black pepper, and dried thyme. Stir until well mixed.
Add the drained tuna, cooked noodles, and frozen peas to the bowl. Gently fold to combine all ingredients evenly.
Transfer the mixture to a greased 9×13 inch baking dish. Sprinkle shredded cheddar cheese evenly over the top.
Sprinkle crushed potato chips over the cheese layer for a crunchy topping.
Bake uncovered for 25-30 minutes until the casserole is bubbly and the topping is golden brown.
Remove from oven and let stand for 5 minutes before serving.
In my kitchen, I usually use a simple baking dish and a trusty skillet to keep things easy. Serving it with a crisp green salad or some fresh bread rounds out the meal nicely. I’ve also tried adding a little extra cheddar on top just before baking for a cheesier finish, though sometimes I skip the chips and sprinkle breadcrumbs instead — not sure if it’s better, but it’s a nice change.
If you’re feeling adventurous, adding a squeeze of lemon juice to brighten up the flavors or stirring in some fresh herbs at the end can be a nice twist. I haven’t tested all these variations extensively, but they’ve worked well enough in a pinch.
FAQ
Can I use tuna packed in oil? Yes, but drain it well to avoid excess greasiness.
What if I don’t have sour cream? Greek yogurt can be a decent substitute, though it might change the texture slightly.
Can this be made ahead? You can prepare it up to the baking step and refrigerate; just add a few extra minutes to bake time when ready.
Is the potato chip topping essential? Not at all. It adds crunch, but you can skip or replace it with breadcrumbs or crushed crackers.
Give this casserole a try next time you want something comforting without the usual milk-based creaminess. It’s an easy, approachable dish that fills the kitchen with warmth and leaves plenty of smiles at the table.
