Ingredients You’ll Need

Grab these bad boys—serves 6, because sharing is caring (or not, leftovers rock). Everything’s simple; no hunting for obscure spices.

• 2 lbs ribeye steak, thinly sliced (or whatever cheap cut you find—life’s too short for perfection)
• 2 green bell peppers, sliced thin (they’re the crunch you crave)
• 1 large onion, sliced (the sweeter, the better—caramelization is key)
• 8 oz mushrooms, sliced (optional, but they add that earthy vibe without the calories)
• 10 slices provolone cheese (the melty star; don’t skimp)
• 1 cup heavy cream (full-fat only—diet versions are a crime)
• 4 oz cream cheese, softened (for that creamy glue)
• 2 tbsp Worcestershire sauce (umami bomb)
• 2 tsp garlic powder (fresh garlic works too if you’re fancy)
• Salt and pepper to taste (duh)
• 2 tbsp olive oil for sautéing (avocado oil if you’re extra healthy)

Pro tip: Slice the steak while it’s half-frozen—makes it way easier, trust me.

Step-by-Step Instructions

Fire up your oven to 375°F (190°C) and let’s do this. Total time? Under an hour. You got this.

1. Heat the oil. Grab a big skillet over medium-high heat. Toss in the sliced steak, season with salt, pepper, and garlic powder. Cook 5-7 minutes until browned. Remove and set aside—don’t overcook, or it’ll be tough as old boots.
2. Sauté the veggies. Same skillet, lower heat to medium. Add peppers, onions, and mushrooms. Cook 8-10 minutes until soft and caramelized. Stir in Worcestershire sauce for that Philly punch. Smells like heaven yet?
3. Make the creamy base. In a bowl, whisk heavy cream and softened cream cheese until smooth. Microwave 30 seconds if it’s stubborn. This is your no-carb “bread” substitute—genius, right?
4. Assemble the magic. In a greased 9×13 baking dish, layer half the veggies, then half the steak. Pour over half the cream mixture. Repeat layers. Top with all 10 provolone slices—cheese blanket incoming.
5. Bake to glory. Pop in the oven for 20-25 minutes until bubbly and cheese is golden. Broil 2 minutes for extra crisp if you’re feeling bold. Let it rest 5 minutes—patience pays off.

Dish it up hot. Pairs killer with a side salad or cauliflower rice. Dig in!

Common Mistakes to Avoid

Nobody’s perfect, but these slip-ups turn gold into mush. Learn from my fails.

• Skipping the veggie caramelization: Raw onions? Blech. Cook ’em low and slow—10 full minutes minimum—or your casserole tastes like a sad salad.
• Overcooking the steak upfront: Rookie move. Brown it quick; it’ll finish in the oven. Tough steak ruins the party.
• Using low-fat dairy: Heavy cream and full-fat cheese are non-negotiable. Skim versions separate and weep—literal tears in your food.
• Forgetting to rest: Straight from oven to plate? Gooey mess. 5-minute chill lets flavors settle.
• Crowding the skillet: Veggies steam instead of sauté. Work in batches if needed—patience, grasshopper.

Avoid these, and you’re golden. Promise.

Alternatives & Substitutions

Not everyone has ribeye on speed dial. No sweat—tweak it your way. IMO, these keep it low-carb and delish.

• Steak swaps: Ground beef (80/20 for fat) or chicken thighs. Turkey works in a pinch, but it’s less juicy.
• Cheese drama: Provolone shortage? Mozzarella or cheddar melt fine. Go wild with pepper jack for heat.
• Veggie rebels: No green peppers? Red or yellow add sweetness. Skip mushrooms if fungi freaks you out—more room for onions.
• Cream hacks: Half-and-half if you’re not strict keto, but heavy cream rules. Greek yogurt (full-fat) for a tangier twist.
• Spice it up: Add 1 tsp smoked paprika or hot sauce to the cream mix. Philly purists might riot, but yum.

Personal fave: Shredded roast beef from last night’s leftovers. Zero effort upgrade.

FAQ’s

Can I make this ahead?

Heck yeah! Assemble, cover, fridge up to 24 hours. Bake straight from cold—add 10 minutes. Freezes like a champ too.

Is it really low carb?

Under 8g net carbs per serving (veggies minus fiber). Track with an app if you’re obsessive—I’m not judging.

What if I hate mushrooms?

Ditch ’em! They just add bulk and flavor. Replace with zucchini or extra peppers—no biggie.

Can I use margarine instead of butter or oil?

Technically, sure, but why punish yourself? Real oil crisps better. Margarine’s for sad toast.

Vegetarian version?

Swap steak for cauliflower or eggplant “meatballs.” Still cheesy bliss, promise.

How do I reheat without sogginess?

Oven at 350°F, covered foil first 10 minutes. Microwave nukes the cheese—avoid if possible.

Kid-friendly?

They’ll devour it if picky. Hide veggies under mega cheese. Winning.
