Portobello and Chickpea Sheet-Pan Supper — The Soup That Started It All

September in Boston has its own quality of light -- the summer heat pulled back, the air doing something that I can only describe as clarifying, the sky a particular shade of blue that doesn't exist in other months. I notice this every year and I notice it the same way every year: as if for the first time, as if this September light is a discovery. It isn't. I have been living in this city for thirty years and I know September's light. It still catches me.

Liam has a best friend. The boy Marcus, who runs fast. They have been building something together in the block corner every day this week according to Miss Alicia's update -- a consistent project, a road and then a city and then something Marcus calls a "road city" which Liam calls a "city road" and which has become an extended argument about naming that neither of them seems to be trying to resolve so much as to sustain as a conversation. They are three-year-olds collaborating and disagreeing. This is friendship. This is exactly what it looks like.

No house news. We are watching the market and waiting. Sean says the fall inventory is typically better than the summer. I am choosing to believe this.

Made minestrone this week -- the big pot with the beans and the greens and the short pasta. Nora ate a bowl and a half and pointed at the pot for more. She is eighteen months old and she eats minestrone. I want to remember this because it is one of those things that is both small and large simultaneously: my daughter eating the soup her grandmother taught me to make, in the kitchen of an apartment where she learned to walk, in the city where she was born.

The minestrone I made this week — the one Nora pointed at for seconds — reminded me that beans and greens and something hearty in the same bowl is just a formula that works, no matter the shape it takes. On nights when I don’t want to tend a big pot, this portobello and chickpea sheet-pan supper gives me that same grounded, September feeling with a fraction of the effort: earthy mushrooms, sturdy chickpeas, roasted until the edges go a little crisp, and the whole apartment smells like something worth coming home to.

Portobello and Chickpea Sheet-Pan Supper

Prep Time: 10 minutes | Cook Time: 30 minutes | Total Time: 40 minutes | Servings: 4

Ingredients

  • 4 large portobello mushroom caps, sliced into 1/2-inch strips
  • 2 cans (15 oz each) chickpeas, drained and rinsed
  • 1 medium red onion, cut into wedges
  • 1 pint cherry tomatoes
  • 3 cloves garlic, minced
  • 3 tablespoons olive oil
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried oregano
  • 1/2 teaspoon cumin
  • 1/2 teaspoon crushed red pepper flakes (optional)
  • Salt and black pepper to taste
  • 2 cups fresh baby spinach or arugula
  • 2 tablespoons fresh lemon juice
  • Fresh parsley, chopped, for serving

Instructions

  1. Preheat. Heat oven to 425°F. Line a large rimmed baking sheet with parchment paper or foil for easy cleanup.
  2. Season the vegetables. In a large bowl, combine the sliced portobellos, chickpeas, red onion wedges, and cherry tomatoes. Drizzle with olive oil and add the garlic, smoked paprika, oregano, cumin, red pepper flakes, salt, and black pepper. Toss well until everything is evenly coated.
  3. Arrange and roast. Spread the mixture in a single layer on the prepared baking sheet — avoid crowding so the edges can caramelize. Roast for 25–30 minutes, stirring once halfway through, until the mushrooms are tender and the chickpeas are lightly crisp.
  4. Add the greens. Remove the pan from the oven and immediately scatter the baby spinach over the hot vegetables. Let it sit for 1–2 minutes to wilt from the residual heat, then toss gently to combine.
  5. Finish and serve. Drizzle the lemon juice over the pan, taste for seasoning, and garnish with fresh parsley. Serve directly from the sheet pan over farro, crusty bread, or on its own.
