french onion baked lentils and farro – smitten kitchen

Caramelize your onions: Warmth butter and olive oil in a big, deep saute pan, ideally one which’s ovenproof, over medium warmth. Add the onions, toss to coat them in butter and oil and canopy the pot. Cut back the warmth to medium-low and let the onions slowly steep for 15 to twenty minutes — they don’t want your consideration. You wish to begin the stirring course of sooner in the event that they’re browning or sticking to the pan. Uncover the pot, increase the warmth to medium-high (for now) and stir in salt — I begin with 2 teaspoons of kosher salt. Cook dinner onions, stirring each couple of minutes (you possibly can test much less usually to start with, and should often stir later within the course of) till the onions are brown, mushy, and candy, about 20 minutes extra. You’ll wish to cut back the warmth to medium as soon as any water the onions emitted has cooked off.

Warmth your oven: To 375°F.

Assemble casserole: Add garlic to the onions and prepare dinner, stirring, one minute. Add sherry, if utilizing, and prepare dinner till it disappears. Add the farro and prepare dinner for two minutes. Add lentils and 6 cups broth and thyme and convey the combination to a simmer. Season properly with salt and pepper as wanted. In case your pan isn’t ovenproof, switch it at this level to a casserole dish.

Bake the casserole: Cowl the pan and bake, stirring about midway via, till the lentils and farro are tender, 40 to 50 minutes. If all the liquid has absorbed, both on the halfway via level or on the finish, add one other 1/4 to 1/2 cup splash of broth. We’re in search of a risotto-like looseness or mild “slosh” within the pan. Fish out thyme stems.

To complete: Sprinkle the dish with gruyere and broil till browned on prime.

Do forward: The dish retains fantastically within the fridge for 4 to five days; rewarm in a 350-degree oven. You may also put together the lentil and farro base a number of days early, rewarm it (it’s going to possible want extra broth at this level), and broil the cheese on prime proper earlier than serving.
