Preheat the oven to 400ºF (205ºC). Line a baking sheet with aluminum foil, and place the peppers on top. Roast the peppers for 35 to 40 minutes, flipping them halfway through baking. The skins of the peppers should have blistered and blackened. Let the peppers cool for 25 to 30 minutes. The peppers will deflate as they cool and the skins should look wrinkly and loose.
Once the peppers are cool enough to handle, peel the thin skins off the peppers. Then, remove the stem and seeds. The seeds will cling onto the flesh of the peppers. To make cleaning easier, I like to rinse the peppers under water to get rid of the seeds easily. Set the peppers aside.
While the peppers are roasting, toast the sliced almonds in a skillet over medium heat for 4 minutes, until they turn slightly golden. Transfer the almonds to a bowl so they stop browning.
Add the peppers, toasted almonds, bread crumbs, 3 teaspoons of gochujang, 2 tablespoons of lemon juice, olive oil, maple syrup, soy sauce, chili flakes, sesame oil, and salt to the bowl of a food processor. Blend until smooth. Taste the sauce and adjust the seasonings to suit your taste. You may want to add more gochujang (I like adding 1 more teaspoon), lemon juice, or salt.
Serve the roasted red pepper dip with vegetables, crackers, or bread. Store leftovers in a tight container and refrigerate for up to 1 week.
