Simmered Fish with Tomatoes & Bacon

 

4 slices bacon

1 red onion, halved and thinly sliced

Kosher salt

Freshly ground black pepper

1/2 tsp. crushed red pepper flakes, optional

One 28-ounce can whole peeled tomatoes

1 1/2 pounds firm white fish, such as halibut, cod, or pollock

Olive oil for drizzling

Chopped fresh chives or parsley, for serving

 

Cook the bacon in a large skillet over medium heat, turning occasionally, until crisp, 5 to 7 minutes. Transfer to a plate. Increase the heat to medium high. To the drippings in skillet, add the onion and season with V2 tsp. salt and several grinds of black pepper. Cook, stirring occasionally, until the onion starts to brown, about 4 minutes. Add the crushed red pepper flakes, if using, and the tomatoes, breaking up with your hands or a spatula to bite-size pieces; season with V2 tsp. salt and more black pepper. Bring to a simmer. Season the fish all over with salt and pepper and nestle in the sauce. Drizzle with oil and cover the skillet. Reduce the heat to low and cook, covered, until the fish is just cooked through, 3 to 5 minutes depending on thickness. Uncover, top with chives, and crumble bacon overtop.
