Instructions
Let’s get cooking! Follow these simple steps and you’ll have this dip ready in no time.
Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures your dip gets that golden, bubbly top. The oven is your friend here—it helps everything come together into a warm, cheesy masterpiece.
Prepare the Onions
Slice your onions thinly, and then caramelize them in a skillet with a little butter over medium heat. Keep stirring every now and then so they cook evenly. You want them to get that rich golden brown color. The smell of caramelizing onions will make your kitchen smell heavenly.
Combine the Dip Ingredients
In a bowl, mix together your caramelized onions, cream cheese, sour cream, mayonnaise, garlic powder, and most of the cheddar cheese (save a little for topping!). Add salt and pepper to taste. Stir it all together until it’s nice and creamy. It should smell so good by now, you might want to sneak a taste.
Assemble the Dip
Transfer the mixture into a baking dish (a 9-inch dish works perfectly). Sprinkle the remaining cheddar cheese over the top for that irresistible cheesy finish.
Bake to Perfection
Place the dish in the preheated oven and bake for about 20-25 minutes, or until the top is golden and bubbly. Keep an eye on it so it doesn’t overcook, but honestly, you’ll be so excited to dig in, it’ll be hard to wait!
Serve and Enjoy
Once your dip is done, let it cool for a few minutes before serving. This dip is best served warm, with tortilla chips, pita bread, or fresh veggie sticks for dipping. If you’re feeling fancy, top it with some chopped green onions or a sprinkle of fresh herbs. Enjoy every cheesy, savory bite!
