In a large pot of salted boiling water, blanch the broccoli florets for about 2-3 minutes, or until they’re tender but still firm. Drain the broccoli and set it aside.
In a skillet over medium-high heat, cook the chopped bacon until it’s crispy. Remove the bacon from the skillet and set it aside on a plate lined with paper towels to drain.
In a small mixing bowl, whisk together the sour cream, mayonnaise, shredded cheddar cheese, and chopped chives until well combined.
In a large mixing bowl, combine the blanched broccoli florets, crispy bacon, and the sour cream mixture. Mix everything together until the broccoli is well coated.
Transfer the mixture to a baking dish and bake it in the preheated oven for about 15-20 minutes, or until the cheese is melted and bubbly.
Remove the dish from the oven and let it cool for a few minutes before serving. Enjoy your keto loaded broccoli!
