This low carb 4-ingredient pastrami bake is the kind of practical, retro supper that earns a permanent spot in the weeknight rotation. It has that unmistakable 1970s casserole charm: simple ingredients, big flavor, and almost no fuss. If you love recipes that feel nostalgic but still fit a modern low carb dinner plan, this one delivers with layers of savory pastrami, melted cheese, and a rich, satisfying texture that makes it hard to believe something so easy can disappear so fast.
Serve this pastrami bake with a crisp green salad, roasted broccoli, dill pickles, or a simple side of coleslaw for a classic deli-style feel. It also works well with steamed green beans or cauliflower for an easy low carb plate, and a spoonful of mustard or a little thousand island dressing on the side can lean it in a Reuben-inspired direction.
Low Carb 4-Ingredient Pastrami Ashcroft Bake
Servings: 6
Ingredients
1 pound sliced pastrami, chopped or torn into bite-size pieces
8 ounces cream cheese, softened
2 cups shredded Swiss cheese
4 large eggs
Directions
1. Preheat the oven to 375°F and lightly grease a medium ceramic casserole dish or 8-inch square baking dish.
2. In a large mixing bowl, beat the cream cheese and eggs together until mostly smooth. A few small cream cheese bits are fine.
3. Stir in the chopped pastrami and 1 1/2 cups of the Swiss cheese, mixing until everything is evenly combined.
4. Spread the mixture evenly into the prepared casserole dish and sprinkle the remaining 1/2 cup Swiss cheese over the top.
5. Bake for 25 to 30 minutes, until the center is set and the top is deeply golden around the edges.
6. Let the casserole rest for 5 to 10 minutes before slicing and serving so it firms up slightly and lifts out in neat squares.
Variations & Tips
Reuben-style twist: Add a thin layer of drained sauerkraut between the mixed filling and the top cheese, then serve with a little thousand island dressing on the side for a deli-inspired version.
Make-ahead tip: You can assemble the casserole a day in advance, cover it, and refrigerate until ready to bake. This is especially handy on busy work nights when dinner needs to be mostly done before the evening starts.
Cheese tip: Swiss gives this bake its classic deli flavor, but provolone or mozzarella can work in a pinch. If you want more browning on top, place the dish under the broiler for 1 to 2 minutes at the end, watching closely.
Texture tip: Letting the casserole rest is important. Right out of the oven it will be very soft, but after a short rest it slices much better and the cheese crisps become even more noticeable.
