Preheat your broiler and set it to high. Next, wash and dry all produce before prepping.

Start Prepping: Chop and dice potatoes into ½-inch cubes. Take the long green pepper and core, seed. Then, slice the onion in half, peel, and dice onion in small cubes. Peel and finely mince garlic. Finely mince jalapeño, removing seeds. If you like more heat, keep some of the seeds in!

Place potatoes in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until very tender, about 12 minutes. Drain and return to pot. Cover to keep warm.

Meanwhile, drizzle a bit of oil in a skillet over medium-high heat. Add the chopped pepper and season with salt and pepper. Cook, stirring occasionally, until lightly browned and softened for about 3-4 minutes. Add onion and season with salt and pepper. Taste as you go as to not over-season. Adjust to your preferences. Cook, stirring, until softened and beginning to brown, 4-5 minutes more. Do not turn up the heat to quicken the cooking process as you may burn the veggies.

Add garlic and as much jalapeño as you’d like (reserving some for garnish) to the pan. Cook, stirring, until fragrant, about 30 seconds. Add beef, seasoning, and a pinch of salt and pepper. Cook, breaking up meat into pieces, until browned and cooked through, about 5 minutes. Add 1 TBSP flour. Cook, stirring to coat, for 1 minute.

Gradually stir in ½ cup water. Add stock concentrate and 1 TBSP ketchup and stir to combine. Simmer until thickened, 1-2 minutes. (Mixture should be the consistency of a very thick chili.) Taste and season with salt and pepper. Remove from heat. (If your pan isn't oven-safe, transfer beef mixture to a baking dish.)

Mash potatoes with 2 TBSP butter, sour cream, and a couple splashes of water (or milk, for a richer experience), as needed, until smooth. Season with salt and pepper. Spread mashed potatoes on top of beef mixture, leaving roughly a 1-inch gap around edge of skillet. Broil until bubbling, about 3 minutes. Sprinkle over as much remaining jalapeño as you’d like (if desired).
