Cooking Steps

Prepare the sweet potato fries
1

Preheat oven to 400 degrees. HINT: For extra crispy fries, place the baking sheet in the oven while it's preheating! Peel the sweet-potato and cut into 1/2-inch matchsticks (like French fries!). On a baking sheet with 1 tablespoon olive oil and season with salt and pepper. Place in the oven and roast for 20 minutes, tossing half way through, until golden brown and crispy.

Prep tomatoes
2

Meanwhile, core and seed 1 tomato, then finely chop. Thinly slice the other tomato widthwise. Halve, peel, and thinly slice the red onion. Drizzle the Portobellos with 1 tablespoon olive oil, season with salt and pepper. Place cap side-up on the baking sheet with the potatoes and roast for 10-12 minutes, until tender. (Keep and eye on them, they'll be done before the potatoes!)

Make tomato-onion jam
3

Meanwhile, make the tomato-onion jam: heat 1 tablespoon olive oil in a medium pan over medium heat. Add the onion and chopped tomato and cook, stirring often, until jammy, 10-15 minutes. Add a splash of water if the jam becomes too thick. Season with salt and pepper.

4

While the jam cooks, separate the head of butter lettuce leaves. Slice the brioche buns in half horizontally. Top with the mozzarella cheese, then place in the oven for about 5 minutes, until the cheese is melted.

Prepare the basil aïoli
5

Make the basil aïoli: chiffonade the basil by stacking the basil leaves on top of each other, then roll them into a cigar, and thinly slice into ribbons. In a small bowl, combine the basil, mayonnaise, and a pinch of salt and pepper.

6

Assemble the burgers: spread each brioche bun with the basil aïoli and top with a Portobello mushroom, a few tomato slices, tomato-onion jam, and lettuce. Serve with the sweet potato fries to the side. Enjoy!
