Start out by preheating your oven to 375 degrees Fahrenheit.
Next, on your stovetop, heat up a large skillet over medium heat. Dice up bacon and add to prepared skillet. As bacon cooks, chop up onion. Continue to fry bacon until it is about half-way cooked and then add in the onion. Cook bacon and onion until bacon is crispy and onions are caramelized and tender, stirring frequently.
There is no need for cooking spray! You can just pour the bacon, onion, and bacon grease into an 8x8" baking dish. Take a spatula and move around the bacon and onion, using the bacon grease to thoroughly coat the bottom and sides of the pan.
Once the baking dish is greased, spread the bacon and onion out across the bottom of the pan.
Crack the eggs into a medium-sized bowl. Whisk together. Add in cottage cheese, salt, and pepper. Whisk again.
Pour egg mixture on top of bacon and onion.
Cook time will vary depending on your oven. Bake for 20 - 30 minutes until center of egg bake is set and an inserted knife comes out clean.
Let cool, slightly. Cut into 4 servings. Top with shredded cheese as you're serving.
