Place the bacon and corn kernels in a large skillet and fry over medium heat, stirring occasionally, until the bacon is crispy. Transfer the bacon and corn to a plate.
Turn on the oven to preheat 180 degrees. Grease a heat-resistant form, measuring 25×35 cm with vegetable oil.
In a saucepan over medium heat, bring the broth to a boil. Pour oatmeal into the broth, reduce heat and cook for about 4-5 minutes, until thickened. Add cream to the flakes, remove the pan from the stove.
Add cheese and green onions to a pan with cereals, mix. Then add eggs and salt, as well as bacon and corn, mix well. Put the resulting mass in a prepared heat-resistant dish and bake for about 40-50 minutes, until golden brown. Remove the cooked casserole from the oven and let stand at room temperature for 10 minutes. Serve the casserole, garnish with green onions.
