Bubble Up Philly Cheese Steak Casserole with Golden Biscuits

Craving the rich, savory flavors of a classic Philly cheesesteak but need an easy weeknight dinner that feeds a crowd? This Bubble Up Philly Cheese Steak Casserole combines juicy ground beef, crisp green bell peppers, and pillowy biscuit pieces drenched in a rich, creamy cheese sauce, all topped with a blanket of melted, golden-brown provolone cheese. It is the ultimate comfort food mashup that comes together in under an hour.

Philly cheesesteaks are a legendary comfort food, but making individual sandwiches for a hungry family can keep you stationed at the stove for far too long. This casserole version transforms those iconic flavors into a simple, crowd-pleasing bake.

By using refrigerated biscuit dough cut into bite-sized pieces, you create a 'bubble up' effect where the dough rises and bakes directly in the savory sauce. The result is a beautiful contrast of fluffy, tender biscuits and savory, cheesy beef that will have everyone reaching for seconds. It is perfect for busy weeknights, game days, or casual weekend gatherings.

Ingredients

Why this recipe works

The magic of this bubble up casserole lies in the unique cooking method of the refrigerated biscuit pieces. As the casserole bakes, the starch in the dough absorbs the surrounding moisture and savory juices from the cooked ground beef and green peppers.

This prevents the biscuits from drying out, keeping them incredibly soft and pillowy on the inside while the exposed tops turn beautifully golden and crisp. The creamy cheese sauce acts as a barrier, locking in moisture and ensuring that every single bite is packed with rich, savory flavor.

Using ground beef instead of traditional shaved ribeye makes this recipe highly accessible, budget-friendly, and incredibly quick to prepare. Sautéing the beef with fresh green bell peppers first allows the meat to absorb the sweet, earthy notes of the pepper while releasing its own savory fats.

When combined with the creamy cheese sauce and topped with mild, melt-friendly provolone cheese, you achieve the perfect flavor balance of a classic cheesesteak without any of the tedious griddle work. It is a foolproof method that delivers consistent results every time.

Notes and substitutions

Selecting the right ingredients is key to achieving the perfect texture in this dish. For the biscuits, standard refrigerated flaky or buttermilk biscuits work best. Avoid using oversized 'grands' style biscuits unless you cut them into smaller, eighth-sized pieces to ensure they bake all the way through without leaving raw dough in the center.

For the cheese sauce, a high-quality jarred cheese sauce or a simple homemade cheddar sauce will provide the creamy base needed to coat the biscuits. Ensure the green peppers are diced uniformly so they cook evenly alongside the beef.

Provolone is the traditional choice for a classic Philly flavor profile, offering a mild, slightly tangy taste and an excellent, stretchy melt. If you prefer a stronger flavor, you can substitute a portion of the provolone with sharp cheddar or even Monterey Jack for an extra kick. A sturdy, 9x13-inch ceramic or glass baking dish is the ideal equipment for this recipe, as it distributes heat evenly and prevents the bottom of the casserole from burning before the biscuits are fully cooked through.
