There’s nothing quite like pulling a bubbling tuna noodle casserole out of the oven on a busy weeknight. This dish saved my sanity during those hectic months when the kids were little and dinner felt like an impossible task. It’s the kind of meal that transforms simple pantry staples into something everyone actually wants to eat.
I’ve been making this kosher version for years, and honestly, it’s become one of our family’s most requested dinners. The key difference from traditional recipes is using a kosher-style white sauce instead of cream of mushroom soup. I make a simple roux with flour and non-dairy milk, then add plenty of mushrooms and herbs. The result is actually more flavorful than the canned soup version, plus you control the salt and texture.
Why This Kosher Tuna Casserole Works So Well
What really makes this casserole work is cooking the noodles just until they’re barely tender. They’ll finish cooking in the oven, so if you start with mushy pasta, you’ll end up with something pretty unappetizing. I use wide egg noodles because they hold up well and grab onto that creamy sauce. The frozen peas add a pop of color and sweetness that balances the tuna perfectly.
The Secret to Perfect Noodle Texture
This feeds a crowd and reheats beautifully, making it perfect for Shabbos prep or when you’re hosting family. Serve it with a simple green salad or some roasted vegetables. The leftovers are even better the next day, which is saying something for a casserole.

Ingredients
Method
- Preheat oven to 350°F. Grease a 9x13 inch baking dish with cooking spray or oil.
- Cook egg noodles according to package directions until just al dente (they should still have a slight bite). Drain and set aside.
- Heat 2 tablespoons olive oil in a large skillet over medium heat. Add mushrooms and cook for 5-6 minutes until golden and most of the liquid has evaporated.
- Add onion to the skillet and cook for 3-4 minutes until softened. Add garlic and cook for another 30 seconds until fragrant.
- Sprinkle flour over the vegetables and stir constantly for 1 minute to cook out the raw flour taste.
- Gradually whisk in the non-dairy milk, making sure to break up any lumps. Cook for 3-4 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.
- Stir in salt, pepper, and thyme. Remove from heat and gently fold in the drained tuna, breaking it into bite-sized chunks.
- Add the cooked noodles and frozen peas to the tuna mixture, stirring gently to combine everything evenly.
- Transfer the mixture to the prepared baking dish and spread it out evenly.
- In a small bowl, mix panko breadcrumbs with remaining 1 tablespoon olive oil. Sprinkle over the top of the casserole.
- Bake for 25 minutes until the top is golden brown and the edges are bubbling. Let cool for 5 minutes before serving.
- Garnish with fresh parsley and serve immediately.
