Start by pulling those frozen broccoli florets out of the freezer. Set them aside for a little while so they can thaw out. This not only helps with cooking but also cuts down on the time it takes to prepare the quiche.

Grab your skillet and toss in the bacon. Cook it over medium-low heat until it turns a deep golden brown and crispy. This usually takes about 6-8 minutes. Transfer the crispy bacon to a paper towel-lined plate to drain any excess grease. Pour out most of the grease from the skillet, but leave a little to flavor the veggies.

Crank up the heat to medium-high and add the thawed broccoli florets along with half of the diced onion. Sauté them in the residual bacon grease for about 4-5 minutes or until the broccoli is tender and no longer cold. Once done, transfer the broccoli and onion mixture to a cutting board and roughly chop the florets into smaller, bite-sized pieces. This will make them easier to eat in the quiche.

While you're chopping, preheat your oven to 350ºF. This ensures your quiche bakes evenly when it’s ready.

In a medium bowl, whisk together the eggs, whole milk, Romano cheese, garlic powder, and a touch of seasoning salt. Make sure all the ingredients are well combined, so every bite is deliciously flavorful.

Spray a 9-inch pie plate with non-stick spray (or butter if you prefer) to prevent sticking. Now it’s time to layer in goodness! First, scatter the chopped broccoli and onion mixture into the dish. Follow with half of the shredded cheddar, and crumble the crispy bacon over the top. Gently stir these three ingredients together to mix them up a bit.

Now, place your pie plate on a baking sheet for easier transport. Carefully pour the egg mixture over the bacon, broccoli, and cheddar. Finish by sprinkling the remaining cheddar on top. Bake the quiche in the oven for 50-55 minutes. You'll know it’s done when the center is puffed and golden brown around the edges.

Once the crustless quiche is baked to perfection, let it cool for a few minutes before slicing it into eight pieces. Serve warm or at room temperature as you like.
