Roasted Cauliflower Grilled Cheese

Roasted Cauliflower Grilled Cheese with 

Greens and Mustard Aioli

(from A Little Bit Crunchy A Little Bit Rock and Roll)

(Adapted from Daphne Oz)


1 large yellow onion, sliced thin

4 tablespoons extra virgin olive oil, divided

1 medium sized head cauliflower, florets removed from core

salt and fresh cracked black pepper

10-12 slices whole wheat panini-style bread

1 cup washed baby arugula or baby greens

8 ounces sharp cheddar cheese, grated

softened butter

Mustard Aioli

2 tablespoons mayonnaise

1 tablespoon dijon mustard

1 jalapeño, minced fine

1 clove garlic, minced

pinch salt


1. Preheat your oven to 425 degrees F.

2. Toss the cauliflower florets on a rimmed sheet pan with 2 tablespoons olive oil and a little salt and pepper. Roast for 20 minutes, stirring half way through.

3. In a medium sized skillet, heat the remaining 2 tablespoons of oil. Add the sliced onion and a small pinch of salt. Caramelize the onions down for about 20-25 minutes, stirring occasionally.

4. Meanwhile, stir the ingredients for the aioli together and set aside.

5. When the cauliflower is done cooking, give it a rough chop on a cutting board so all the florets are small and bite-sized. Place the cauliflower in a bowl and add the caramelized onions and the grated cheese.

6. Set a pan or stove-top griddle or outdoor grill to a medium low heat. Spread 1 slice of bread with some aioli. Top with a little of the cauliflower mixture, a small handful of greens, and more cauliflower mixture. Butter the bread lightly and cook until both sides are golden brown and the cheese is melted.
