In a cast iron skillet, add olive oil and heat 3-5 minutes
Add chopped onions and cook for about 5 minutes until they become soft and start to brown
Add in shredded brisket, seasonings, garlic and beer. Stir until well combined.
Take brisket mixture out of cast iron skillet and add to a bowl. Add about 1/3 of the cheese to this bowl and combine until it melts in with the rest of the mixture.
Heat oven to 400 degrees
Spray the bottom of the cast iron skillet. Layer chips on bottom of skillet. Add half of the brisket to the chips, sprinkle with half of the remaining cheese.
Layer on another layer of chips, add the remaining brisket mixture and top with cheese.
Cook at 400 for about 10-12 minutes, or under cheese fully melted
Top with your favorite toppings and serve immediately
Notes
Toppings: Add on toppings of your choice on top. In the photo, we added olives, chives and jalapeño pepper slices. Cheese Substitution: You can substitute Monetary Jack and Cheddar Cheese with no problem. Beer Substitutions: You can substitute ½ broth for the beer. You can swap the beer for vegetable, chicken, or beef broth. The flavor will be slightly different, but still tasty. Also look for non alcoholic beer. Cheese Isn't Staying Melted: When using cheese from the bag that is already shredded (like most of us do) the cheese will harden back up quickly because there are additives in the bag to make the cheese not stick. The fresh "you grated it yourself" cheese is the best. If you want the cheese to really be gooey for a long time, you can use a jarred cheese as it's runny and doesn't harden up
