This oven baked 4-ingredient Amish cream of onion noodle dish is one of those cozy, back-pocket recipes you can throw together on a busy weeknight. It’s inspired by the simple, pantry-friendly casseroles you still see at church potlucks and small-town gatherings all over the Midwest. You literally pour canned cream of onion soup and two more ingredients over uncooked egg noodles in a baking dish, slide it into the oven, and let the magic happen. It comes out creamy, comforting, and kid-friendly, with almost no prep or cleanup.
Serve these creamy noodles with something that adds a little color and crunch, like steamed green beans, a simple side salad, or roasted carrots. Garlic bread or dinner rolls are great for soaking up the extra sauce. For a heartier plate, add sliced roast chicken, meatloaf, or baked pork chops on the side. A light fruit salad or applesauce works nicely for kids and keeps the meal feeling homey and balanced.
Oven Baked Amish Cream of Onion Noodles
Servings: 4-6

Ingredients
8 oz uncooked wide egg noodles (about half a 16 oz bag)
2 cans (10.5 oz each) condensed cream of onion soup
1 1/2 cups whole milk
1/2 cup salted butter, melted (or very soft)
Directions
Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish with a little butter or nonstick spray so the noodles don’t stick.
Spread the uncooked egg noodles evenly in the bottom of the prepared baking dish. Try to keep them in a fairly even layer so they cook through at the same rate.
In a medium bowl, whisk together the canned cream of onion soup and the milk until smooth and well combined. The mixture should be pourable and creamy.
Whisk the melted (or very soft) butter into the soup mixture until it’s fully blended. This helps keep the noodles tender and gives the sauce that rich, homestyle flavor.
Pour the cream of onion mixture evenly over the uncooked egg noodles in the baking dish, making sure to cover as many noodles as possible. Gently press down with the back of a spoon to help the liquid settle around the noodles.
Cover the baking dish tightly with aluminum foil. This traps the steam and allows the noodles to soften and cook in the sauce without drying out.
Bake, covered, in the preheated oven for 35–40 minutes, until the noodles are tender when you poke them with a fork and the sauce is bubbling around the edges.
Carefully remove the foil (watch out for steam), give the noodles a gentle stir to coat everything in the creamy sauce, and bake uncovered for an additional 5–10 minutes if you’d like the top to set a little more.
Let the casserole rest for about 5 minutes before serving so it can thicken slightly. Spoon into bowls or onto plates and serve warm.
Variations & Tips
For picky eaters, keep the base recipe as-is and serve any extras on the side so they can choose what to add. To make it more of a full meal, stir in 1–2 cups of cooked, shredded chicken, ham, or browned ground beef after baking, then pop it back in the oven for 5–10 minutes to warm through. If you’d like a little color and veggies, you can scatter 1–2 cups of frozen peas or mixed vegetables over the uncooked noodles before pouring on the soup mixture; they’ll cook right along with the noodles. For extra richness, swap half of the milk for heavy cream. If you prefer a bit of a crust on top, remove the foil at the end, sprinkle with crushed butter crackers or plain bread crumbs mixed with a little melted butter, and bake until golden. To lighten it up slightly, use 2% milk and reduce the butter to 1/4 cup; the texture will be a bit less rich but still creamy. Leftovers reheat well with a splash of milk to loosen the sauce, making it a good make-ahead option for busy school nights.
