Ingredients
- Sweet onions: The long slow caramelization makes these buttery and rich Choose onions that feel heavy for their size
- Oil: Helps the onions get silky and brown Go for a high heat oil like avocado or canola for best browning
- Salt and pepper: Brings out savory flavors and balances sweetness of the onions Use flaky salt for extra punch
- Vegan burger patties: The base of the sandwich Choose patties that can crumble easily after thawing
- Vegan cheese: Melts beautifully over the hot burger mixture Look for ones labeled creamy melt or deli style
- Hoagie rolls: Slightly crusty outside with a soft inside Toasting adds great crunch
- Tomatoes: Adds freshness and a juicy bite Pick tomatoes that are ripe yet still firm
- Shredded lettuce: Gives that signature classic chopped cheese contrast Choose crisp green leaf or romaine
- Vegan mayo or ketchup: The creamy or tangy finish that ties everything together Pick your personal favorite sauce
Step-by-Step Instructions
- Sauté the Onions:
- Add oil to a large heavy skillet over medium heat Drop in the sliced onions and sprinkle with salt Stir to coat all the onions with the oil and salt This draws out their moisture and sets them up for caramelizing Cook them slowly stirring and scraping the bottom every few minutes Plan for at least twenty five to thirty five minutes The onions will first soften then slowly turn golden blond then deep and jammy Turn the heat a touch lower if they ever show signs of burning
- Crumble and Cook the Vegan Burgers:
- Once the onions are beautifully caramelized scoot them to one side and add the thawed vegan burger patties Scatter a little extra salt and pepper Chop the burgers into small crumbles using a spatula Stir to mix them with the onions and let everything cook until heated through and thickened The mixture should reach at least one hundred sixty five degrees for best flavor and texture If your patties need specific handling always check the package
- Melt the Cheese:
- Spread the crumbly burger and onion mixture into four even piles right in the pan Top each with one slice vegan cheese Cover the skillet with a lid and let it sit off the heat for about three to four minutes until the cheese is perfectly melted into every nook
- Assemble the Sandwiches:
- Open up your hoagie rolls and layer in lettuce and sliced tomatoes first for extra crunch and barriers against sogginess Pile on a quarter of the hot cheesy burger mixture for each roll Spoon on mayo ketchup or both and press the top half of the roll on
- Serve:
- Slice each sandwich in half or leave whole Serve piping hot with your favorite pickles or chips The juices will run and the flavors will mingle just like a deli classic

The sweet onions really make this sandwich unforgettable I love how the caramelized onions almost taste buttery even without any actual butter It always reminds me of weeknights when everyone would crowd into the kitchen just to sneak a taste of the onions straight from the pan
Storage Tips
Wrap leftovers tightly in aluminum foil or keep in an airtight container and refrigerate for up to three days The mixture can be reheated gently in a skillet or microwave To keep the bread from getting soggy store bread and filling separately and assemble just before eating
Ingredient Substitutions
