2 cups water
1 cup (updated) semi-pearled farro
1/2 large onion
2 cloves garlic
9 ounces grape or cherry tomatoes
1 1/4 teaspoons kosher or coarse sea salt
Up to 1/4 teaspoon red pepper flakes (to taste)
1 tablespoon olive oil, plus extra for drizzling
Few basil leaves, cut into thin ribbons (optional)
Grated parmesan cheese, for serving (optional)
Place water and farro in a medium saucepan to presoak (5 to 10 minutes are probably sufficient) while you prepare the other ingredients. Adding each ingredient to the pot as you finish preparing it, cut onion in half again, and very thinly slice it into quarter-moons. Thinly slice garlic cloves as well. Halve tomatoes. Add salt, pepper flakes (to taste) and 1 tablespoon olive oil to pan, and set a timer for 30 minutes. Bring uncovered pan (no lid necessary) up to a boil, then reduce to a gentle simmer, stirring occasionally. When the timer rings, the farro should be perfectly cooked (tender but with a meaty chew), seasoned and the cooking water should be almost completely absorbed. If needed, cook it for 5 additional minutes, until farro is more tender.
Transfer to a wide serving bowl. If there’s enough leftover cooking liquid to be bothersome, simply use a slotted spoon to leave the amount you wish to behind. Drizzle farro lightly with additional olive oil, scatter with basil and parmesan. Eat immediately.
