This is a relatively small side dish, but you can absolutely double or triple it in a larger dish.
1 pound (455 grams) baby carrots, the peeled and bagged kind5 tablespoons (75 grams) unsalted butter, divided¾ cup panko-style plain breadcrumbsKosher salt1 medium shallot, chopped2 garlic cloves, minced3 tablespoons (25 grams) all-purpose flour1 cup (235 ml) vegetable brothFreshly ground black pepper3 tablespoons minced parsley, or a mix of herbs you like with carrots such as chives and dill, divided2 tablespoons capers, drained1 cup (85 grams) grated gruyere or comte cheese
Heat your oven: To 350°F (176°C).
Prepare the carrots: Our biggest enemy here is how water-logged baby carrots come in bags. But, it’s worth the trouble for the ease! Drain the carrots (there’s a puddle at the bottom of the bag just waiting to splash you) and put them in a bowl lined with a few layers of paper towels for 10 minutes before starting. Quarter the carrots lengthwise and return them to the towel-lined bowl while you work on the other elements.
Make the brown butter crumbs: In a large skillet, melt 2 tablespoons (30 grams) of the butter over medium heat and keep cooking it, stirring here and there, until the butter has brown flecks all over and smells dreamy. Add the breadcrumbs and two pinches of salt to the pan and toast, stirring, until they’re golden brown all over. Scoop the crumbs out and set them aside.
Make the sauce: Heat the remaining 3 tablespoons (45 grams) of butter and brown it, too. Once browned, increase the heat to medium-high and add the shallots. Cook the shallots until tender and beginning to brown at the edges, 3 to 5 minutes. Add the garlic and cook for one minute more. Add the flour and cook until it disappears; it will look like a chunky paste. Add the broth, stirring until the flour mixture disperses. Bring the sauce to a simmer and season with 1 teaspoon kosher salt (I’m using Diamond brand; start with half of other brands) and many grinds of black pepper. The sauce is going to seem too thick but that’s intentional; more water will come out of the carrots as they bake. Add carrots and stir to combine, cooking them together for one minute. Stir in 2 tablespoons of the herbs.
Assemble and bake: Transfer the carrots and their sauce to a 1-quart baking dish. Cover tightly with foil and bake for 45 minutes to 1 hour, until carrots are tender (spear with a knife or toothpick to check for no resistance). Increase oven temperature to 400°F (205°C). Transfer dish briefly to a heatsafe surface. Remove foil, stir in capers. Combine cheese and toasted crumbs and sprinkle on top. Return to the oven for 10 minutes, or until cheese is melted. For more color on top, run the pan briefly under your oven’s broiler.
Serve: Sprinkle with remaining 1 tablespoon herbs and dig in.
Do ahead: You can prepare the dish up to the point when it goes in the oven and pause for a few hours, or overnight in the fridge. You could also pause right before adding the cheese and crumbs for the final bake; this would be ideal to do right before serving. Leftovers can be reheated in a 350-degree oven.
