This oven baked 4-ingredient Amish sour cream noodle casserole is the kind of humble, comforting dish that shows up on a lot of Midwestern Sunday supper tables. My grandma made a version of this after church—nothing fancy, just pantry staples layered into something unbelievably creamy with those irresistible golden-browned edges. Amish and farmhouse-style cooking leans heavily on simple ingredients used generously: plenty of noodles, tangy dairy, and a touch of cheese for richness. If you’re looking for a low-effort, kid-friendly, budget-conscious main dish that tastes like it took all afternoon, this is it.
Serve this casserole hot, straight from the oven, with something fresh and crisp alongside to balance the richness. A simple green salad with a sharp vinaigrette, sliced cucumbers with a sprinkle of salt and vinegar, or steamed green beans all work well. On heartier nights, add buttered peas or roasted carrots and a basket of crusty bread or dinner rolls to mop up the creamy sauce. It also pairs nicely with roasted chicken or baked ham if you want to stretch it into a larger Sunday-style spread.
Oven Baked 4-Ingredient Amish Sour Cream Noodle CasseroleServings: 6
Ingredients
12 oz wide egg noodles
2 cups full-fat sour cream
2 cups shredded mild cheddar cheese, divided
1 teaspoon kosher salt (plus more for salting the pasta water)
Directions
Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch white casserole dish or similar baking dish and set aside.
Bring a large pot of well-salted water to a boil. Add the egg noodles and cook just to al dente according to package directions, usually 6–8 minutes. The noodles will continue to cook in the oven, so avoid overcooking.
Drain the noodles thoroughly and return them to the warm pot. Let them sit for 1–2 minutes so excess steam escapes; this helps the sauce cling instead of thinning out.
Add the sour cream, 1½ cups of the shredded cheddar, and the kosher salt to the warm noodles. Stir gently but thoroughly until every noodle is coated in the creamy mixture and the cheese begins to melt. Taste and adjust the salt if needed.
Transfer the noodle mixture to the prepared casserole dish, spreading it into an even layer. Use a spatula to nudge the noodles into the corners so they bake evenly.
Sprinkle the remaining ½ cup shredded cheddar evenly over the top. This will form the golden, slightly crisped layer around the edges as it bakes.
Bake, uncovered, for 25–30 minutes, or until the casserole is bubbling around the edges and the top is melted and lightly golden brown. If you like deeper browning, you can leave it in for an extra 5 minutes, watching carefully.
Remove the casserole from the oven and let it rest for 5–10 minutes before serving. This short rest helps the sauce thicken slightly so the portions hold together while still staying luxuriously creamy inside.
Scoop into bowls or onto plates, making sure to get some of the browned edges with each serving for the best texture and flavor contrast.
Variations & Tips
Because this recipe is intentionally pared down to four ingredients, any additions will move it beyond the original concept—but once you’ve tried the base version, you can absolutely play. For a touch more flavor without adding new ingredients, use extra-sharp cheddar instead of mild, or swap in half mozzarella for a stretchier pull. If you want a bit of tang, stir in a spoonful of the hot pasta water into the sour cream before mixing; it loosens the texture and helps it coat the noodles even more evenly. To make it a more complete one-dish meal, you can fold in cooked, crumbled sausage or ground beef, or a handful of thawed frozen peas, though that does take it beyond the traditional Amish-style simplicity. For a slightly lighter feel, you can replace up to 1/2 cup of the sour cream with plain Greek yogurt, understanding the sauce will be a little less rich and a bit more tangy. Leftovers reheat well in a covered dish in a low oven with a splash of milk or cream stirred in to bring the creaminess back. If you’d like a more pronounced browned top, finish the casserole under the broiler for 1–2 minutes, watching closely so the cheese doesn’t scorch.
