What You’ll Need (Ingredients)
- 4 medium zucchinis (straight and firm for easy stuffing)
- 1 pound thinly sliced beef (ribeye is classic; sirloin or flank works too)
- 1 large yellow onion, thinly sliced
- 1 green bell pepper, thinly sliced
- 1 red bell pepper, thinly sliced (optional but adds sweetness)
- 2 cloves garlic, minced
- 6–8 slices provolone cheese (or 1½ cups shredded)
- 2 tablespoons olive oil, divided
- 1 tablespoon unsalted butter (for flavor and sear)
- 1 teaspoon kosher salt, plus more to taste
- ½ teaspoon black pepper
- ½ teaspoon smoked paprika (optional but recommended)
- ¼ teaspoon crushed red pepper flakes (optional)
- 1 teaspoon Worcestershire sauce (umami boost)
- Fresh parsley, chopped, for garnish (optional)
Step-by-Step Instructions
- Preheat and prep the boats. Heat your oven to 400°F (205°C).
Slice zucchinis lengthwise and scoop out the centers with a spoon, leaving about ¼ inch border. Lightly score the flesh. Brush with 1 tablespoon olive oil and sprinkle with a pinch of salt and pepper.
Place on a baking sheet, cut-side up.
- Par-roast the zucchini. Bake for 10–12 minutes until just tender but not mushy. You want structure—think al dente zucchini canoes.
- Cook the veg. In a large skillet over medium heat, add remaining 1 tablespoon olive oil and the butter. Toss in onions and peppers with a pinch of salt.
Cook 6–8 minutes, stirring, until softened and lightly caramelized. Add garlic for the last 30 seconds. Transfer to a bowl.
- Sear the beef. Bump the heat to medium-high.
Add the sliced beef in a single layer. Season with salt, black pepper, smoked paprika, and red pepper flakes. Sear 2–3 minutes, tossing, until just cooked.
Stir in Worcestershire. Don’t overcook—chewy steak is a crime.
- Combine filling. Return peppers and onions to the skillet with the beef. Toss to mingle.
Taste and adjust seasoning. If it needs more oomph, add a splash more Worcestershire or a pinch of salt.
- Fill and top. Divide the steak mixture among the zucchini boats. Drape with provolone slices or sprinkle with shredded cheese, covering the tops generously.
- Final bake. Return to the oven for 6–8 minutes, until the cheese is melted and bubbly.
For extra golden bliss, broil for 1–2 minutes at the end. Watch closely—bubbles good, burn bad.
- Finish and serve. Garnish with chopped parsley. Let rest 3 minutes so the juices settle.
Serve hot. Prepare for compliments you absolutely deserve.
Keeping It Fresh
Storage: Cool completely, then store in an airtight container for up to 3 days. Keep the zucchini and any extra filling separate if possible to avoid sogginess.
Reheat: Oven at 350°F for 10–12 minutes or air fryer at 320°F for 5–7 minutes.
Microwaves work but soften the zucchini more than ideal—still tasty, just less snap.
Make-ahead: Par-roast zucchini and cook filling up to 24 hours ahead. Assemble and bake right before serving. Weeknight magic trick, unlocked.
Freezing: Not recommended for assembled boats (texture suffers).
You can freeze the cooked steak-pepper-onion mix for up to 2 months; thaw and assemble fresh with zucchini.
Benefits of This Recipe
- Lower-carb without sacrifice. You get the cheesesteak vibes and protein punch, minus the bread bloat.
- Family-friendly. It’s colorful, cheesy, and hand-holdable for the rebels at the table.
- Budget smart.
- Meal-prep friendly. The components reheat well, and you can build boats on demand.
- Micronutrient boost. Zucchini brings vitamin C, potassium, and fiber to the party.
Pitfalls to Watch Out For
- Overcooking the zucchini. If it’s mushy, it won’t hold the filling. Par-roast lightly and finish only until cheese melts.
- Steaming the steak. Crowding the pan traps moisture. Cook in batches if needed to get that sear.
- Underseasoning. Zucchini is mild.
Salt each layer (zucchini, veg, steak) and taste your filling before stuffing.
- Watery boats. Scoop enough seeds out and pre-bake. If your zucchini is extra watery, sprinkle a tiny bit of salt after scooping, let sit 10 minutes, and pat dry.
- Cheese choice fails. Some cheeses split or oil out. Provolone melts smoothly; mozzarella works too.
Save cheddar for a variation, not the classic vibe.
Recipe Variations
- Mushroom Lover’s Edition: Add 8 ounces sliced cremini mushrooms with the onions and peppers for deep umami.
- Spicy “South Street” Style: Swap provolone for pepper jack, add pickled jalapeños, and finish with hot cherry pepper relish.
- Cheez Whiz Throwback: Go full-on Philly nostalgia with warmed Cheez Whiz drizzled over the finished boats. Not subtle. Extremely delicious.
- Chicken Cheesesteak Boats: Use thinly sliced chicken thighs or breasts; season with a pinch of Italian seasoning and proceed as written.
- Garlic-Herb Twist: Stir 1 tablespoon chopped fresh parsley and 1 teaspoon fresh thyme into the filling; finish with a squeeze of lemon.
- Keto Max: Add bacon crumbles and swap Worcestershire for coconut aminos if you’re avoiding gluten (FYI, check labels).
- Italian Deli Style: Use sliced provolone and add roasted red peppers, plus a dusting of dried oregano before baking.
FAQ
What’s the best cut of beef for Philly Cheesesteak Zucchini Boats?
Ribeye is the gold standard thanks to its marbling and tenderness.
Sirloin, flank, or shaved steak from the butcher also work great—just slice thinly against the grain so it stays tender and cooks fast.
Do I need to salt the zucchini beforehand?
Not always. If your zucchinis are firm and fresh, a quick par-roast is enough. For extra watery ones, sprinkle with salt after scooping, rest 10 minutes, then pat dry to reduce moisture.
Can I make this dairy-free?
Yes.
Use a dairy-free provolone-style cheese or a good melting vegan mozzarella. Add a little nutritional yeast to the filling for cheesy depth without the dairy.
How do I slice beef thin at home?
Freeze the steak for 20–30 minutes to firm it up, then use a sharp knife to shave it into thin slices against the grain. Ask your butcher to shave it for you if you want to skip the effort—IMO worth it.
What sides go well with this?
Keep it light with a crisp Caesar, garlicky green beans, or a tomato-cucumber salad.
If you want more comfort, roasted potatoes or sweet potato fries are a win.
Can I grill the zucchini instead of baking?
Totally. Brush with oil and grill cut-side down over medium heat 4–5 minutes to soften and get marks. Fill, top with cheese, and close the grill lid to melt.
How do I avoid tough steak?
High heat, short cook time, and thin slices.
Pull it the moment it’s just cooked; overcooking turns it from tender to tire rubber fast.
