Crustless Onion and Cheese Bake

Follow our step-by-step guide on how to make Crustless Onion and Cheese Bake.

1. Step 1

   Start by preheating your oven to a cozy 350°F (175°C) and greasing an 8-inch square baking dish or a pie pan to ensure your delicious creation doesn’t stick.

2. Step 2

   While the oven warms up, grab a skillet and melt a delightful mix of butter and olive oil over medium-high heat.

3. Step 3

   Toss in the diced onion and let it sizzle, stirring occasionally, until it transforms into a beautifully caramelized golden treat—this should take about 10 minutes.

4. Step 4

   Once the onions are perfectly cooked, transfer them to a plate and allow them to cool slightly; this step adds a wonderful depth of flavor to your dish.

5. Step 5

   In a mixing bowl, whisk together heavy whipping cream, eggs, salt, and black pepper until everything is well blended and creamy.

6. Step 6

   Now, fold in the shredded mozzarella cheese, the rich grated Parmesan cheese, and those lovely caramelized onions you set aside.

7. Step 7

   Pour this luscious mixture into your prepared baking dish, spreading it out evenly to ensure every bite is packed with flavor.

8. Step 8

   Slide the dish into your preheated oven and let it bake for about 35 minutes.

   You’ll know it’s ready when the eggs are set, and a knife inserted in the center comes out clean.
