Preheat the oven to 350°F. In a large skillet, cook the bacon over medium-high heat until crisp. Remove using a slotted spoon to paper towels to drain, then chop.
Reserve 2 Tbsp bacon drippings in the pan. (Freeze the remaining drippings) Over medium-high heat cook the 3 diced fresh jalapenos just until softened, about 2 minutes.
Add the green onions to the pan. Cook for 1 minute longer. (Reserve some green onions for garnishing.)
Next, add 1/2 of the chopped cooked bacon, cream cheese, sour cream, mayonnaise, ranch salad dressing mix and hot sauce. Turn the heat off and mix just until fully combined. Remove from the stovetop. (You can also transfer to a large bowl to combine.)
Stir half (1 cup) of the shredded colby jack cheese into the mixture, Transfer to a baking dish or oven safe skillet. (If the skillet you're using is oven safe, you can use the same pan.)
Top with the remaining 1 cup colby jack cheese. Place into the oven and bake for 30 minutes.
Arrange jalapeno slices on top. Continue to bake for another 10 minutes or just until bubbly and the cheese is golden brown.
Garnish with the remaining bacon and green onions and serve with tortilla chips, fritos scoops, veggies or crackers for dipping.
