Portabella Mushroom Pizza Hamburgers are a delicious light alternative to heavily breaded sandwiches. The grilled seasoned burgers nestle in the grilled mushroom cavities. Then they’re topped with mozzarella or grated parmesan cheese and finished with a squirt of tangy homemade pizza sauce.
Portabella Mushroom hamburgers easy to fix and eat
Have you ever ordered a sandwich at a restaurant, and once it’s delivered wondered how the heck you’re going to eat it? Your mouth would have to be the size of a hippo’s just to get a bite. Why are restaurants making sandwiches so huge they end up falling apart?
This happened just last Saturday when I ordered a Corvina sandwich. Hubby ordered a portabella sandwich, and Jason, our son, ordered a lamb burger. The waiter brought the sandwiches and all we could do was stare at the mountain of layers.
Where to start? My sandwich was heavy enough that I had to do a double arm curl to lift it to my mouth. As I took a bite, a nice chunk of red tomato slid out of the bun into the linen napkin on my lap.
I put the sandwich back down on the plate and pressed down on the bun. The lettuce, tomato, and onion began to peek out from between the bun. I grabbed the knife and split the bun with its contents in half.
Now I had two skyscraper pieces with the filling threatening to spill out piece by piece. I looked at my Hubby and Jason — they were in the same predicament.
Thank goodness the meal was with the family because it was messy. I ate the sandwich partly by hand but mostly with a fork being careful not to have any more pieces land in my lap.

“Should we put the hamburgers on a bun?” asked Honey. He was unwrapping the package of ground beef.
“No!” I quickly replied. “I’d rather eat my meal off my plate and not pick the pieces off my lap.”
He pointed to the giant mushrooms on the counter. “How about grilling them along with the burgers? We can put the grilled patties on top of the mushrooms.”
“That’s a great idea!” I said. “Why don’t we give them an Italian flair? We can add mozzarella on top. You know, something like our Grilled Portabella Mushroom alla Caprese.”
“Sounds good,” he said. “Why don’t we make it like pizza and we’ll put some of our pizza sauce on it?”
“Oh, yummy! We’ll call it Portabella Mushroom Pizza Hamburgers! I’m so glad I thought of it!”
Honey wasn’t saying anything he was just giving me “the look.” “What?” I asked. He still didn’t say anything. “Okay, okay. You thought up the initial idea. But I finished it!!”
Italians really have a hard time conceding. 😉
Forming the Portabella Mushroom Pizza Hamburgers
For the burgers, we use about 6 to 8 ounces of ground beef for each patty. If you prefer, you can use ground turkey, chicken, pork or anything else you like.
We mix in one tablespoon of Tuscan seasoning, salt, and pepper. If your Italian seasoning contains salt you don’t have to add any more.
How to prepare the pizza hamburger for grilling:
- In a bowl break the ground beef into little pieces.
- Sprinkle the Italian seasoning, salt, and pepper over the meat.
- Add 2 Tablespoons minced onion and 2 teaspoons minced garlic.
- Add 2 Tablespoons grated parmesan cheese.
- Using your hands or fork, gently mix together. Avoid overworking, the more you work it, the tougher it gets.
- Gently shape the mixture into patties and using your thumb, make a shallow depression in the center to prevent the center from puffing up during cooking.
How to Prepare the Portabella mushrooms for grilling:
- Remove debris or sand with a soft-bristled vegetable brush.
- Wipe the mushrooms with a slightly water-dampened paper towel.
- Pat the mushroom dry.
- Cut the stems off of each portabella mushroom.
- Use a spoon to scrape out the dark gills on the underside of the mushroom caps. Discard.
- Brush both sides of mushrooms with olive oil.
Portabella mushrooms are ideal with hamburgers, they have about 30 calories and have no fat or cholesterol. The Mayo Clinic even uses the mushroom as a substitute for the hamburger.
Cooking the Portabella Mushroom Pizza Hamburger
Spray the grill grates with vegetable oil and then preheat the gas grill to 350 F. Once it’s preheated put the hamburger and portabella mushrooms, cavity side up, on to cook. The mushroom will cook faster than the meat. Don’t flip the mushroom over, just move it to the side away from the heat.
Once you put the burgers on a medium-hot grill, do not, I repeat do not press or squish them down with a spatula. I’m sure you’ve seen it done but it’s wrong. That releases all of the fat and the juicy goodness right onto the flames. Let them cook on one side for about 5 minutes then gently flip and brown on the other side.
Now’s the time to add the cheese. Mozzarella would be ideal since it continues the Italian flavor. Close the lid so the heat stays in and the cheese melts. This time we sprinkled grated parmesan cheese on it, normally we put mozzarella on top but we didn’t want to hide the meat for the photo.
Plating the Portabella Mushroom Pizza Hamburgers
Once the hamburgers were done we put each patty into the cap cavity of each mushroom. Both the meat/mushroom combo went on top of bibb lettuce leaves. A sprinkle of our Tangy Pizza Sauce around the meat, mushrooms, and lettuce leaves finished the dish. Use our pizza sauce recipe or one of your own.
Serve immediately and enjoy!!
Tutti a tavola è pronto!
