Gather all of your ingredients and preheat your oven to 400\u2109. (You\u2019ll also need some all-purpose flour and vegetable oil, but I accidentally left them out of this photo!)<\/p>\nSaut\u00e9 the onion:<\/strong> Add 1 diced onion to a saut\u00e9 pan over medium heat with 1\u00a0Tbsp olive oil, 1\u00a0tsp salt, 1\u00a0tsp black pepper, and 1\u00a0tsp cumin. Saut\u00e9 for about 4 minutes or until the onion softens.<\/p>\nBake the peppers: <\/strong>While you saut\u00e9 the onions, add 4 poblano peppers to a parchment-lined baking sheet. Don\u2019t add any oil or seasonings to the peppers; we want to bake them as is.<\/p>\nBake the peppers in the preheated oven for 10 minutes. Then, flip them and bake for another 10 minutes. While the peppers bake, you can start on the sauce (see below).<\/p>\nOnce done, the peppers should be browned, and the skin should be wrinkled, as shown here.<\/p>\nSteam the peppers: <\/strong>Immediately transfer the baked peppers to a heat-safe bowl and cover them securely with plastic wrap. The residual heat will steam the peppers and loosen the skin even more. Let them steam for about 10 minutes.<\/p>\nMake the sauce: <\/strong>Pour 1\u00a028 oz.\u00a0can of crushed tomatoes, 1\u00a010 oz.\u00a0can of diced tomatoes with green chiles, and 5\u00a0cloves minced garlic to the pan with your saut\u00e9ed onion. Stir and turn the heat down to low, and simmer for 15-20 minutes.<\/p>\nBlend the sauce (optional):<\/strong> Let the sauce cool for at least 5 minutes (you shouldn\u2019t add hot sauces to a blender straight from the stove) and then pour it into a blender.<\/p>\nBlend the sauce until smooth, and then pour it back into your original saut\u00e9 pan and simmer on low.<\/p>\nPrep the peppers:<\/strong> After the peppers have steamed for 10 minutes or so, gently peel them and cut a slit down the middle of each with a knife. They\u2019ll be very tender and easy to slice through, so be careful not to cut all the way through to the other side. You want the pepper to function as a vessel for the cheese!<\/p>\nGently remove the seeds with a spoon. It can be a little tricky (again, you don\u2019t want to accidentally split the pepper beyond the slice we\u2019ve already made), but it\u2019s easy to do with a little patience and a spoon.<\/p>\nStuff the peppers: <\/strong>Carefully tuck \u00bc cup of shredded queso cheese inside each pepper, being careful not to tear them. If you can fit more cheese, then go for it! But don\u2019t overstuff them. Each side of the cut should be able to overlap to close them once stuffed.<\/p>\nMake the batter: <\/strong>Separate 3 egg yolks into a small bowl and the whites into a medium mixing bowl. <\/p>\nUse a hand mixer to whip the egg whites into stiff peaks. When you lift the beaters, the peaks should stand straight up without drooping.<\/p>\nNow add one yolk at a time, whipping after each addition, until combined and fluffy.<\/p>\nPour \u00bd\u00a0cup flour into a shallow bowl and gently roll each stuffed pepper in the flour (be sure to hold the opening closed) and then into the egg mixture, making sure it\u2019s lightly coated all over. Do this to all of them while \u00bd cup vegetable oil heats in a second pan. They will be kind of foamy-looking and very messy, but it makes the fry batter nice and light!<\/p>\nFry the peppers: <\/strong>Place each pepper into the oil and fry for about 2-3 minutes on each side or until golden and crispy. I recommend doing this in batches as they are very fragile.<\/p>\n
