Step-by-Step Instructions

Cook the Potatoes: In a large pot, bring water to a boil. Add the peeled and cubed potatoes and cook for about 20 minutes, or until soft. Drain the potatoes and return them to the pot.
Mash the Potatoes: Using a potato masher or ricer, mash the potatoes to your desired consistency. If you like them creamy, mash them well.
Add Butter and Spices: Incorporate the butter, salt, pepper, onion powder, and garlic and herb seasoning into the mash. Mix well until the butter is melted and thoroughly blended.
Mix in Cream: Gradually add the milk (or heavy cream) while continuing to mash until the mixture reaches your desired creaminess.
Incorporate Creamy Ingredients: Stir in the sour cream and mayonnaise for extra creaminess, ensuring they are well combined.
Fold in Toppings: Mix in 1 cup of the shredded cheddar cheese, the crumbled bacon, and half of the green onions. Blend until just combined.
Prepare for Baking: Preheat your oven to 375°F (190°C). Grease a 9×13 inch casserole dish with butter.
Assemble the Casserole: Transfer the potato mixture into the greased casserole dish and spread it evenly. Top with the remaining cheddar cheese.
Add Garnishes: Sprinkle additional chopped green onions and leftover bacon on top.
Bake: Place the casserole in the oven and bake uncovered for 25-30 minutes, or until the cheese is melted and bubbly.
Serve: Remove from the oven and allow it to cool for a few minutes before serving hot.

Pro Tips

For the best texture, use a potato ricer for ultra-fluffy mashed potatoes.
You can customize the cheese; feel free to use a Mexican cheese blend or add Parmesan for extra flavor.
Cooking the bacon until crispy adds a nice crunch that contrasts beautifully with the creaminess of the potatoes.
If you want a bit of a kick, consider adding a pinch of cayenne pepper or some jalapeños into the mix.

Common Mistakes

Overcooking potatoes: Make sure to test them with a fork and avoid boiling until mush.
Not enough seasoning: Taste your mixture before baking; you want it well-seasoned to really stand out.
Skipping the cooling time: Let the casserole set for a few minutes after baking to allow the flavors to meld and make serving easier.

Variations

Add other toppings like broccoli or cheese curds for a loaded twist.
Swap out the bacon for sautéed mushrooms or caramelized onions for a vegetarian version.
Mix in some cooked and crumbled sausage for an even heartier dish.
