How to Make Golden Potatoes O’Brien Breakfast Casserole
This Golden Potatoes O’Brien Breakfast Casserole recipe is designed for ultimate ease and maximum satisfaction, requiring minimal effort for a dish that’s both incredibly delicious and wonderfully filling. The magic lies in its simple assembly and the harmonious blend of tender potatoes, savory sausage, and vibrant peppers, all bound together by a creamy egg mixture. Expect a preparation time of approximately 20 minutes, with a bake time of 35-45 minutes, making it perfect for busy weekdays or leisurely weekend brunches.
Step-by-Step Instructions
- Preheat and Prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray.
- Cook the Sausage: Heat the olive oil in a large skillet over medium heat. Add the breakfast sausage and cook, breaking it up with a spoon, until browned and cooked through. Drain off any excess grease and set the sausage aside.
- Sauté the Vegetables: In the same skillet (without cleaning it), add the chopped yellow onion, green bell pepper, and red bell pepper. Sauté over medium heat for about 5-7 minutes, or until the vegetables are tender-crisp.
- Par-boil the Potatoes: While the vegetables are sautéing, place the cubed Yukon Gold potatoes in a large pot. Cover them with cold water by about an inch. Bring to a boil over high heat, then reduce heat to medium and simmer for about 8-10 minutes, or until the potatoes are just fork-tender. You don’t want them mushy; they should still have a slight bite. Drain the potatoes thoroughly.
- Assemble the Casserole: In the prepared baking dish, evenly spread the par-boiled potatoes. Top with the cooked sausage and the sautéed bell peppers and onions.
- Prepare the Egg Mixture: In a large bowl, whisk together the 8 large eggs, ½ cup milk, ½ teaspoon salt, and ¼ teaspoon black pepper. If you desire a little heat, add the optional pinch of cayenne pepper.
- Add Cheese: Sprinkle ½ cup of the shredded cheddar cheese over the potato, sausage, and pepper mixture in the baking dish.
- Pour and Top: Pour the egg mixture evenly over the ingredients in the baking dish. Make sure the egg mixture seeps down into all the nooks and crannies. Sprinkle the remaining ½ cup of shredded cheddar cheese over the top.
- Bake: Cover the baking dish loosely with aluminum foil. Bake for 20 minutes.
- Uncover and Finish Baking: Remove the aluminum foil and continue baking for another 15-25 minutes, or until the casserole is set in the center and the cheese on top is golden brown and bubbly. A knife inserted into the center should come out clean.
- Rest and Serve: Let the Golden Potatoes O’Brien Breakfast Casserole rest for 5-10 minutes before slicing and serving. This allows it to set up nicely, making it easier to cut.
