How to Make Easy Keto Philly Cheesesteak Casserole

Step 1: Easy Keto Philly Cheesesteak Casserole prep and browning the beef

In Easy Keto Philly Cheesesteak Casserole, I start by prepping the beef. Pat the meat dry and slice it as thin as you can. This helps browning happen quickly and stay tender through baking.

Heat a large skillet with olive oil over medium-high heat. Add the beef in a single layer and sear until lightly browned. Work in batches to avoid crowding and steaming rather than browning.

Remove browned beef and set aside with its juices to stay juicy. Season with salt, pepper, and paprika for classic Philly flavor. Return to the plate and wipe the pan if it spattered.

Back in the pan, I let flavors mingle briefly to bloom. This short rest keeps the beef juicy for baking. Set the beef aside with seasoned juices for the next step.

Step 2: Easy Keto Philly Cheesesteak Casserole: sauté the peppers and onion

In the same skillet, add a little oil if needed. This prevents sticking and helps peppers brown evenly. Then I’m ready to sauté the peppers and onion.

Toss in green and red peppers and onion until they glisten. The colors wake up the plate and the palate for sure. Sauté until they soften and release natural sweetness.

Cook four to five minutes, until softened and lightly caramelized. I love a touch of brown for depth. Keep the veggies moving to prevent scorching and uneven browning.

Stir in garlic and cook for about 30 seconds, fragrant. That quick kiss brightens the entire casserole without bitterness. Then we move to building the creamy sauce.

Step 3: Easy Keto Philly Cheesesteak Casserole: build the creamy sauce

For Easy Keto Philly Cheesesteak Casserole, if the pan looks dry, splash in cream. This thin layer helps the sauce cling to every bite. We’re adding richness without flour or starch.

Pour in heavy cream and cream cheese, whisk until smooth. Keep whisking until there are no lumps. Let the mixture simmer gently to blend flavors beautifully.

Let the sauce loosen slightly and thicken with gentle heat. Stir often so it stays silky, not glossy or gritty. Taste and adjust salt to your preference before pouring.

Season with salt and pepper to balance the richness. If you like warmth, a pinch of paprika does wonders. Allow flavors to mingle for a minute before assembly.

Step 4: Easy Keto Philly Cheesesteak Casserole: combine, transfer, and top

Return beef to the skillet and mix with vegetables for Easy Keto Philly Cheesesteak Casserole. Toss until everything looks glossy and well coated with sauce. This creates a cohesive filling ready for the bake.

Spoon the mixture into a greased casserole dish. Spread evenly so it bakes and browns uniformly. A smooth, even layer helps every bite feel right.

Top with shredded provolone or mozzarella for that melty crown. Press gently so cheese hugs the filling instead of floating. The topping should melt into a glossy, bubbly crust.

Bake at 375°F for 20–25 minutes until bubbly and golden. Let the casserole rest five minutes before serving. That short pause keeps portions tidy and flavorful.

Step 5: Easy Keto Philly Cheesesteak Casserole: bake, rest, and serve

Garnish with sliced green onions for color and freshness. A bright finish that invites you to taste immediately. Then slice and serve with confidence, steam rising from the dish.

If you’re in a rush, this dish still shines. It adapts easily with leftovers or pantry swaps. You’ll want it on repeat as a weeknight favorite.

Leftovers reheat well in the microwave or oven. Store in an airtight container for 3–4 days. Print-friendly copies make weeknight planning effortless.
