Cheesy Tater-Topped Chili

I saw this prepared on Rachael Ray's television show and it looked so good. It looks like a true comfort meal.

• Ready In: 40 mins
• Serves: 6

Ingredients

• 6  large potatoes, peeled and cut into chunks
• 2  tablespoons extra virgin olive oil or 2  tablespoons  corn oil or 2  tablespoons  vegetable oil
• 2 1⁄2 lbs  ground sirloin
• 1  medium onion, finely chopped
• 3  garlic cloves, chopped
• 3  tablespoons chili powder
• 2  tablespoons cumin
• 2  tablespoons  smoked paprika
•  cinnamon, pinch
•  salt, to taste
• 1⁄4 cup tomato paste
• 1 (12 ounce) bottle stout beer (could just use extra beef stock or beef broth)
• 1 -1 1⁄2 cup  beef stock
• 4  tablespoons butter
• 7  scallions, white parts finely sliced (use tender green parts for garnish)
• 1 -1 1⁄2 cup milk
• 2  egg yolks
• 2  cups  extra-sharp white cheddar cheese, shredded

Directions

1. In a large pot, boil the potatoes until they are fork-tender.
2. While the potatoes are coming up to a boil, preheat a deep skillet or wide, heavy-bottomed pot over medium-high heat.
3. Add the olive oil and ground beef and crumble up the meat as it cooks, using the back of a wooden spoon or potato masher, for about 8 minutes, until brown and caramelized.
4. Add the onions, garlic, chili powder, cumin, smoked paprika, cinnamon, salt and tomato paste to the meat and cook another 5 minutes.
5. Add the beer and stock, and stir to loosen any bits from the bottom of the pan.
6. Reduce the heat and simmer for 10-15 minutes, until thickened.
7. Season the chili with salt to your taste.
8. Once the potatoes are done cooking, drain and return them back to the same pot.
9. Place the potatoes back over the heat, shaking them around a bit to dry them out.
10. Add the butter and the whites of the scallions to the potatoes, and sauté the scallions 1-2 minutes, until tender.
11. Remove the potatoes from the heat then add in the milk, egg yolks, salt and ground black pepper. Mash them up with the potatoes masher.
12. Fold the cheese into the potatoes and allow it to melt.
13. At this point the chili should be ready to be poured into a casserole dish and topped with the cheesy scallion potatoes.
14. Place the chili tater-topped casserole into the oven and brown the top, about 2-3 minutes.
15. Garnish with the reserved green scallion tops and serve.
