📝 Ingredients:

• 4 large sweet onions (like Vidalia), thinly sliced
• 4 tablespoons butter
• 1 cup shredded cheddar cheese
• ½ cup grated Parmesan cheese
• 1 cup crushed buttery crackers (like Ritz)
• ½ cup milk
• ½ cup sour cream
• 2 eggs, beaten
• Salt and black pepper to taste
• Optional: 1 teaspoon garlic powder or thyme for extra flavor

🍳 Instructions:

Step 1: Preheat your oven

• Set the oven to 350°F (175°C).

Step 2: Prepare the onions

• Peel and thinly slice the onions.
• In a large skillet, melt the butter over medium heat.
• Add the onions and cook for about 10-12 minutes, stirring occasionally, until soft and translucent. Don’t let them brown too much.

Step 3: Mix the base

• In a large bowl, combine:
  • Cooked onions
  • Sour cream
  • Milk
  • Eggs
  • Salt, pepper, and optional seasonings
• Stir well to mix everything together.

Step 4: Assemble the casserole

• Grease a 9×9-inch or similar baking dish.
• Pour the onion mixture into the dish.
• Sprinkle the shredded cheddar evenly on top.

Step 5: Add the topping

• In a separate bowl, mix crushed crackers with Parmesan cheese.
• Sprinkle the cracker topping evenly over the casserole.

Step 6: Bake it!

• Place the dish in the preheated oven.
• Bake for 25–30 minutes or until the top is golden brown and the casserole is set.

✅ Tips for Beginners:

• Use pre-sliced onions if cutting onions is tough.
• Don’t skip preheating the oven—it helps the casserole cook evenly.
• Let the casserole rest for 5 minutes before serving so it holds its shape better.
