These Queso Stuffed Poblanos are filled with sauteed mushrooms, spinach, rice, and a homemade sauce and topped with melty cheese.



For the Sauce (makes extra to save for later)

  • 1 28-ounce can diced tomatoes
  • half of a red onion, chopped (reserve a small amount for the mushrooms later)
  • a big handful of cilantro
  • 1 jalapeƱo pepper (remove the seeds and ribs if you want it mild)
  • 1 cup water
  • 1 1/2 teaspoons salt

For the Poblano Peppers

  • 2 tablespoons butter
  • 8 ounces fresh mushrooms
  • 8 ounces fresh spinach
  • 5 poblano peppers
  • 1 cup uncooked white rice
  • 1 1/2 cups shredded queso melt cheese (just about any kind of cheese will work)
  • 23 tablespoons flaxmeal (optional)


  1. For the sauce: Preheat the oven to 400 degrees. In a food processor or blender, puree the sauce ingredients until mostly smooth. Set aside.
  2. For the filling: Melt the butter in a large skillet over medium high heat. Add the reserved red onions and mushrooms; saute until browned and softened. Add the spinach; saute until just wilted. Add the rice and stir around in the pan to coat. Add 2 cups of the sauce from step one, stir, and simmer over medium low heat. Continue to simmer, adding a little water if necessary, until the rice is cooked (about 20 minutes). Stir in one cup of the cheese. If the mixture seems too runny, add a few tablespoons of the flax meal to act as a binder that will soak up excess moisture and hold everything together nicely. Taste and season with salt if needed.
  3. For the peppers: Cut the poblanos in half lengthwise and remove the ribs and seeds. Top each half with a few spoonfuls of filling and a pinch of the remaining shredded cheese. Bake for 15-20 minutes, until the poblanos are softened and the cheese is melted.


With this amount of filling, I filled about 8-10 poblano halves.
