A Daily Dinner: Portobello Burgers with Roasted Tomatoes

Portobello burgers, with roasted tomatoes, smoked mozzarella, and kale chips

Who says you need meat to make a perfect burger?

Ryan and I didn’t really have any doubts as to the merits of a good portobello burger, but after this dinner last week, we think even the most steadfast carnivore could be swayed.

The whole dinner was inspired by a recipe in My Father’s Daughter, a new cookbook written by Gwyneth Paltrow (yes, that Gwyneth Paltrow).

Slow-Roasted Tomatoes

First, Paltrow’s recipe calls for on-the-vine tomatoes to be halved and slow-roasted in the oven, with just a bit of olive oil and salt, for 3-5 hours. We let our first batch roast for nearly the full five hours before pulling out shriveled, tangy little gems, but they were so good that we ate them up instantly!

We roasted our second batch (the ones you see here) for just over two hours and were rewarded with still plump, juicy tomatoes—perfect for topping a burger.

Portobello mushrooms marinate in a marinade of lemon juice, olive oil, salt, pepper and garlic

Next, we let our giant portobellos marinate with some smashed garlic cloves, salt, pepper, olive oil and lemon juice for about 15 minutes. In the meantime, I sliced up a sweet onion and a few slices of smoky fresh mozzarella.

We forewent the fries this dinner in lieu of a healthier option—kale chips. We first made kale chips last year and have since become addicted to their salty bite and bitter green flavor.

How to make easy healthy kale chips

After tearing the kale into pieces (removing any thick ribs first), we put them on a baking sheet with salt, red pepper and a bit of olive oil and roasted them at 300 degrees for about 20 minutes. The result: earth-shatteringly crunchy, emerald green chips. Every bit as decadent as your typical salted crisps.

The portobellos were cooked in a sauté pan for about 10 minutes, along with the sliced onion, until they both were lusciously tender and packed full of juice and flavor.

Vegetarian Portobello Burger with Smoked Mozzarella and Grilled Onion

The final, simple step: build your burger however you like! We used sesame brioche buns, which we piled high with our mushrooms, grilled onions and slices of mozzarella cheese. We ran the finished product until the broiler for a minute (who doesn’t love warm, gooey mozzarella?) and then topped with aforementioned tangy tomatoes.

Biting into this burger was no different than taking a bite out of a medium-rare beef patty and even just as enjoyable, especially with the company of a crisp Shiner Ruby Red beer (imported from New Jersey).

    Everything about this recipe looks and sounds delicious! We love the idea of kale chips instead of fries. Not completely sold on the portobello mushroom, but we’re definitely willing to try it with your stamp of approval as well as Gwyneth Paltrow’s!

    Love the Shiner! I’m Texas-born as well and after spending 4 years in NYC for school, I moved back to Austin for work. I’m bummed I never found Shiner up there myself, but I’m happy to see you representing TX.

    Love your post…I never thought Gwyneth Paltrow cooks. No wonder she is so pretty and fit. This recipe is so healthy and deliciously appealing. I’ll probably have grilled onions on the side. I am sure my husband would have lotsa’ cheese to go with these burgers…
