Ingredients

• 1 tablespoon olive oil
• 1 large yellow onion, chopped
• 2 cloves garlic, minced
• 4 cups small broccoli florets (about 1 head of broccoli)
• 1 pound Yukon Gold potatoes, peeled and cut into 1/2-inch cubes
• 1 cup shredded carrots
• 1 pint cherry tomatoes, halved
• 1 1/2 cups cooked chicken, shredded or diced (rotisserie chicken works great!)
• 1 cup milk (whole or 2%)
• 1/2 cup heavy cream
• 2 large eggs, lightly beaten
• 1 teaspoon dried dill
• 1/2 teaspoon dried thyme
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 2 cups shredded sharp cheddar cheese, divided
• 1 cup shredded mozzarella cheese, divided
• 2 tablespoons fresh parsley, chopped (for garnish, optional)

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
2. Prepare the potatoes: Place the cubed potatoes in a medium saucepan and cover with cold water. Bring to a boil over medium-high heat and cook for 5-7 minutes, or until just tender-crisp. Drain well and set aside. This par-cooking step ensures the potatoes will be perfectly tender in the casserole.
3. In a large skillet or Dutch oven, heat the olive oil over medium heat. Add the chopped onion and cook for 5-7 minutes, until softened and translucent. Add the minced garlic and cook for another minute until fragrant.
4. Add the broccoli florets and shredded carrots to the skillet. Cook for 3-5 minutes, stirring occasionally, until the vegetables start to soften slightly.
5. Remove the skillet from the heat. In a large mixing bowl, combine the cooked onion, garlic, broccoli, carrots, par-cooked potatoes, cherry tomatoes, and shredded cooked chicken. Gently toss to combine.
6. In a separate medium bowl, whisk together the milk, heavy cream, beaten eggs, dried dill, dried thyme, salt, and black pepper until well combined. This is your creamy binder.
7. Add 1 cup of the shredded cheddar cheese and 1/2 cup of the shredded mozzarella cheese to the vegetable and chicken mixture. Pour the creamy binder over everything and gently stir until all ingredients are evenly coated.
8. Transfer the entire mixture to the prepared 9×13 inch baking dish, spreading it out evenly.
9. Sprinkle the remaining 1 cup of shredded cheddar cheese and 1/2 cup of shredded mozzarella cheese over the top of the casserole.
10. Bake for 30-40 minutes, or until the casserole is golden brown and bubbly on top, and the internal temperature reaches 165°F (74°C). If the cheese starts to brown too quickly, you can loosely cover it with foil.
11. Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting time is crucial as it allows the casserole to set, making it easier to portion and ensuring it holds its shape beautifully.
12. Garnish with fresh chopped parsley, if desired, and serve hot.

Cooking Tips and Variations

For the best Weeknight Wonder Casserole experience, consider these tips and unleash your creativity with variations. To ensure your potatoes and other hard vegetables cook evenly, always par-cook them slightly before adding them to the casserole. This prevents them from being undercooked while the rest of the ingredients get perfectly tender. Don’t overcrowd your baking dish; a single, even layer allows for proper heat circulation and browning. A crucial tip for casseroles is the resting period after baking; letting it sit for 5-10 minutes allows the ingredients to settle and the sauce to thicken, resulting in cleaner slices. For an extra golden and crispy cheese topping, you can pop the casserole under the broiler for the last 2-3 minutes, but watch it carefully to prevent burning.

When it comes to customization, the possibilities are endless! For protein swaps, instead of chicken, try cooked ground beef or turkey, sliced smoked sausage, diced ham, or even canned chickpeas or black beans for a vegetarian option. If using raw ground meat, brown it first and drain any excess fat before adding it to the casserole. For vegetable variations, feel free to use what you have on hand or what’s in season. Spinach, bell peppers, zucchini, mushrooms, or even frozen mixed vegetables (thawed and drained) can be excellent additions. Just be mindful of vegetables that release a lot of water, like zucchini, and consider sautéing them briefly beforehand.

Cheese choices can dramatically alter the flavor profile. While cheddar and mozzarella provide classic comfort, experiment with Gruyère for a nutty depth, Monterey Jack for extra meltiness, or a sprinkle of Parmesan for a salty kick. To boost the flavor even further, consider adding a pinch of red pepper flakes for a subtle heat, a dash of Worcestershire sauce to the liquid mixture for umami, or a squeeze of lemon juice after baking for brightness. Fresh herbs like rosemary or thyme can also be incorporated with the dried herbs for a more vibrant aroma. This casserole is also fantastic for meal prep; assemble it completely without baking, cover tightly, and refrigerate for up to 24 hours. When ready to bake, add an extra 10-15 minutes to the cooking time.

Storage and Reheating

Storing your Weeknight Wonder Casserole correctly ensures you can enjoy its deliciousness for days to come. Once the casserole has cooled completely to room temperature, cover the baking dish tightly with plastic wrap or aluminum foil, or transfer individual portions to airtight containers. Stored in the refrigerator, the casserole will remain fresh and delicious for up to 3-4 days. This makes it an excellent option for meal prepping and enjoying convenient lunches or dinners throughout the week.

For longer storage, this casserole freezes beautifully. Once completely cooled, you can either wrap the entire baking dish (if freezer-safe) tightly with several layers of plastic wrap and then foil, or divide it into individual portions and place them in freezer-safe containers or heavy-duty freezer bags. Label with the date. Frozen, the casserole will maintain its quality for up to 2-3 months. When you’re ready to enjoy a frozen casserole, it’s best to thaw it overnight in the refrigerator before reheating.

Reheating is simple, whether from the fridge or thawed from the freezer. To reheat a large portion or the entire casserole from the refrigerator, preheat your oven to 350°F (175°C). Cover the casserole loosely with foil to prevent the top from over-browning and bake for 20-30 minutes, or until heated through. If reheating individual servings, the microwave is your best friend. Place a portion on a microwave-safe plate, cover loosely (a damp paper towel helps keep it moist), and heat on high for 2-4 minutes, stirring halfway through, until thoroughly warmed. For a crispier top, individual portions can also be reheated in a toaster oven or air fryer until hot and slightly browned.

Frequently Asked Questions

What kind of potatoes work best in this casserole?

Yukon Gold potatoes are highly recommended for this casserole because their waxy texture holds up well during cooking, preventing them from becoming mushy, while still becoming wonderfully tender. Russet potatoes can also work, but they tend to be starchier and might break down more easily. Red potatoes are another good option for their firm texture.

Can I make this casserole ahead of time?

Absolutely! This casserole is perfect for making ahead. You can assemble the entire casserole, including the cheese topping, up to 24 hours in advance. Cover it tightly with plastic wrap and refrigerate. When you’re ready to bake, remove it from the fridge about 30 minutes before baking to allow it to come closer to room temperature, then bake as directed, adding an extra 10-15 minutes to the cooking time to ensure it heats through evenly.

How can I make this casserole vegetarian?

Making this casserole vegetarian is very easy. Simply omit the cooked chicken and, if desired, replace it with an equal amount of canned chickpeas or black beans (drained and rinsed), or a plant-based ground meat substitute that has been cooked according to package directions. You can also increase the amount of vegetables to make it heartier, adding extra mushrooms, bell peppers, or spinach.

Can I use different cheeses?

Yes, feel free to experiment with different cheeses to suit your taste! While cheddar and mozzarella provide a classic, comforting flavor and excellent melt, you could try Gruyère for a nutty, complex flavor, Monterey Jack for a milder, creamier melt, or even a blend of Italian cheeses. Just ensure they are good melting cheeses for that perfect bubbly crust.
