These oven baked roast beef and Jarlsberg crescent half moons are the kind of easy party snack that earns instant repeat requests. With just refrigerated crescent dough, deli roast beef, and creamy nutty Jarlsberg, they come together quickly and bake into flaky, savory pockets that feel a little nostalgic and a little special at the same time. They are ideal for cookouts, game days, casual holiday gatherings, or any time you need a warm appetizer without a long ingredient list.
Serve them warm on a platter with mustard, horseradish sauce, or a simple creamy dip on the side. They also fit nicely into a bigger spread with potato salad, pickle spears, fresh fruit, chips, or a crisp green salad, and for a Labor Day or tailgate table they pair especially well with baked beans and cold sparkling drinks.
Oven Baked 3-Ingredient Roast Beef and Jarlsberg Crescent Half Moons
Servings: 8 half moons
Ingredients
1 tube refrigerated crescent roll dough (8-count)
8 thin slices deli roast beef
4 slices Jarlsberg cheese, cut in half
Directions
1. Preheat the oven to 375°F and line a baking sheet with parchment paper or lightly grease it.
2. Unroll the crescent dough and separate it into 8 triangles.
3. Place 1 slice of roast beef on each triangle, folding it as needed to fit, then top each with a half slice of Jarlsberg cheese.
4. Roll up each triangle from the wide end toward the point, curving the ends slightly to form half moons. Arrange them seam-side down on the prepared baking sheet.
5. Bake for 11 to 14 minutes, or until the crescents are puffed and deep golden brown and the cheese is melted.
6. Let cool for 3 to 5 minutes before transferring to a serving platter. Serve warm.
Variations & Tips
Add a spread: If you do not mind going beyond three ingredients, a thin swipe of Dijon mustard or prepared horseradish sauce inside each crescent adds sharpness that works beautifully with the roast beef and cheese.
Keep the filling tidy: Avoid overfilling or the cheese may run out too much during baking. Folding the roast beef into compact layers rather than letting it drape over the edges helps the crescents keep their shape.
Try a different cheese: Swiss, provolone, or havarti can stand in for Jarlsberg if needed. Each melts well, but Jarlsberg gives the most traditional mild, buttery flavor for this combination.
Make-ahead tip: You can assemble the crescents a few hours ahead, refrigerate them on the baking sheet, and bake just before serving. They are best warm, when the pastry is crisp and the cheese is soft.
