Ingredients
- 1 lbs yellow squash, sliced thinly
- 1 lbs zucchini, sliced thinly
- 4 tbsp butter, separated
- 2 cups finely chopped sweet onion
- 2 cloves garlic, minced
- 1 can whole kernel corn (15.25 oz), drained
- 1 can cream-style corn (15 oz)
- 1 ½ cups shredded sharp white Cheddar cheese
- 1 cup grated Asiago cheese, split
- 1 ½ cups bread crumbs, split
- ½ cup mayonnaise
- 2 big eggs, whisked
- 1 tsp salt
- 1 tsp ground black pepper
Step 1
To begin, preheat your oven to a cozy 350 degrees Fahrenheit (about 175 degrees Celsius) and generously grease a 9x13-inch casserole dish, ensuring a non-stick cooking experience.
Step 2
In a spacious pan, combine the vibrant zucchini and squash, submerging them in water, then allow them to gently simmer for about 5 minutes on medium-high heat. Once done, drain the veggies and delicately pat them dry between layers of paper towels to rid them of excess moisture.
Step 3
While the vegetables are undergoing their transformation, let's work on infusing flavors. In a skillet, melt 2 tablespoons of butter, then toss in the onion and sauté for a couple of minutes. Introduce the garlic and continue cooking until the onion turns tender and the garlic releases its delightful aroma, around 2 more minutes. Merge the zucchini and squash into this fragrant mix, followed by whole kernel corn, cream-style corn, a generous sprinkle of Cheddar cheese, 1/2 cup of Asiago cheese, 1/2 cup of breadcrumbs, a dollop of mayonnaise, eggs, a pinch of salt, and a dash of pepper. Once everything is thoroughly combined, pour this luscious concoction into your prepared casserole dish.
Step 4
To create a crispy topping, melt the remaining 2 tablespoons of butter in a skillet. Add the remaining 1 cup of breadcrumbs and the remaining 1/2 cup of Asiago cheese, allowing them to meld together beautifully. Sprinkle this delightful mixture over the casserole, adding an extra layer of texture and flavor.
Step 5
Now, let the magic happen in the preheated oven. Bake your creation until it reaches a glorious golden hue, and the casserole sets with the cheese melting beautifully, which should take around 45 to 50 minutes.
Step 6
Embrace the delightful aromas wafting from your oven as you eagerly await the scrumptious masterpiece that awaits you. Enjoy this delightful dish with your loved ones, savoring each bite filled with love and flavor!
Extra Tips & Suggestions
- 1. Keep your zucchini, squash, and corn fresh by storing them in the crisper drawer of your refrigerator. Make sure to place them in separate plastic bags to prevent them from getting soggy.
- 2. When storing zucchini and squash, avoid washing them until you are ready to use them. Excess moisture can lead to premature spoilage.
