My friend’s mom made this hearty dish for the church potluck and the pan was licked clean in minutes

In a large mixing bowl, stir together the sour cream and 1 cup of the shredded cheddar cheese until smooth and evenly combined. This creates the creamy, tangy base that gives the casserole its signature richness. If the sour cream is very cold and stiff, let it sit at room temperature for a few minutes first so it’s easier to mix.
Add the drained egg noodles to the sour cream and cheese mixture. Gently fold everything together until the noodles are evenly coated. Take your time here so you don’t break the noodles too much; you want them well-covered in the creamy sauce so every bite is rich.
Spread the sour cream–coated noodles in an even layer in the prepared glass baking dish. Use the back of a spoon or spatula to nudge the noodles into the corners, keeping the top relatively level so the cheese later melts evenly.
Spoon the warm beef and tomato sauce mixture evenly over the noodles. You can gently swirl it in with a spoon if you like a more marbled look, or leave it layered for a distinct creamy bottom and saucy top—either way, aim for even coverage so no section is dry.
Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top of the casserole, going all the way to the edges. This will form the bubbly, golden, cheesy crust that makes the dish so inviting on a potluck table.
Cover the baking dish loosely with foil, tenting it slightly so it doesn’t stick to the cheese. Bake in the preheated oven for 20 minutes to heat everything through and let the flavors mingle. Then remove the foil and continue baking for another 10–15 minutes, or until the cheese is fully melted, bubbling around the edges, and lightly golden in spots.
Carefully remove the casserole from the oven and let it rest on a cooling rack or trivet for at least 10 minutes before serving. This brief rest helps the creamy sauce thicken slightly so the portions hold together instead of sliding apart when you scoop them out.
For serving, use a large spoon or spatula to scoop generous portions from the glass dish, making sure to dig all the way down to get some of the creamy noodles and saucy beef in each serving. If you are bringing this to a church potluck or gathering, cover the warm dish with foil for transport and set it out with a serving spoon—the pan will likely be licked clean in no time.
Variations & Tips
To keep the spirit of a simple Amish-style pantry casserole while tailoring it to your own table, there are several easy variations. For a slightly lighter version, swap half of the sour cream for plain Greek yogurt; it will still be creamy but with a bit more tang and protein. If you prefer a milder flavor, use a mix of cheddar and mozzarella or Monterey Jack for the topping, which melts into a softer, stretchier layer. You can also trade the tomato pasta sauce for a can of tomato soup plus a splash of water for a more old-fashioned, church-basement taste. For extra vegetables without complicating the recipe, stir in 1–2 cups of thawed frozen peas, corn, or mixed vegetables with the noodles before baking. If your crowd likes a little heat, add a pinch of crushed red pepper flakes or a dash of hot sauce to the meat sauce. Finally, this bakes well ahead: assemble the casserole, cover tightly, and refrigerate up to a day; when ready to serve, bake covered for an extra 5–10 minutes to ensure it heats through before uncovering to brown the cheese.
