Ingredients:

6 potatoes
1280g
1 cup sour cream
230g
1/2 cup milk (1% fat)
120g
1/2 tsp black pepper
1.05g
1/4 tsp salt
1.50g
1/4 tsp garlic powder
0.78g
1/4 tsp onion powder
0.60g
2.50 cups broccoli
230g
1 cup cheddar cheese
110g
1 cup mozzarella cheese
110g
4 cups onion
400g

Instructions:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Potatoes:
- Wash and scrub the potatoes thoroughly.
- Pierce each potato a few times with a fork.
- Place the potatoes on a baking sheet and bake for about 45-60 minutes, or until they are tender when pierced with a fork.
3. Cook the Onions and Broccoli:
- While the potatoes are baking, heat a large skillet over medium-high heat.
- Spray or lightly coat the skillet with olive oil, then add the chopped onions.
- Sauté the onions until they become translucent and begin to brown, about 10-15 minutes.
- Steam or blanch the broccoli until it becomes tender but still vibrant green, about 5 minutes. Drain and set aside.
4. Prepare Casserole Mixture:
- Once the potatoes are baked, remove them from the oven and let them cool slightly until they are safe to handle.
- Slice each potato in half lengthwise and scoop out the insides into a large mixing bowl, leaving a thin layer of potato as the shell.
- To the bowl with the potato insides, add the sour cream, milk, black pepper, salt, garlic powder, and onion powder. Mash everything together until smooth and well combined.
- Add the sautéed onions and chopped broccoli to the potato mixture and gently fold them in.
5. Assemble Casserole:
- Lightly grease a 9x13-inch baking dish.
- Spread half of the potato mixture evenly on the bottom of the dish.
- Sprinkle half of the cheddar cheese and half of the mozzarella cheese evenly over the potato layer.
- Spread the remaining potato mixture over the cheese layer.
- Finally, sprinkle the remaining cheddar and mozzarella cheese on top.
6. Bake:
- Return the casserole to the oven and bake at 375°F (190°C) for another 20-25 minutes, or until the cheese is melted, bubbly, and golden brown on top.
7. Serve:
- Remove the casserole from the oven and let it cool for a few minutes before serving.
- Enjoy your delicious twice-baked potato and broccoli casserole with onions!

Tips:

- Make sure to bake the potatoes until they are completely soft. This ensures that your mashed potatoes will be smooth and creamy.

- For an added burst of flavor, consider sautéing the onions before adding them to the casserole.

- If you prefer a crispy top, finish the casserole under the broiler for a few minutes after baking.

- You can add bacon bits or chopped ham to the mixture for a meaty twist.

- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.

Your twice-baked potato and broccoli casserole with onions is now ready to be served. This creamy, cheesy, and veggie-packed dish is sure to be a hit. Enjoy this comforting casserole on its own or paired with your favorite protein for a complete meal.
