Step‑by‑Step Instructions for Broccoli Spinach Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, take a moment to prepare a 9×9-inch baking dish by lightly greasing it with nonstick spray to ensure easy release of your delicious Broccoli Spinach Casserole after baking.

Step 2: Cook the Broccoli
In a microwave-safe bowl, add the frozen broccoli florets and cover them with a lid or microwave-safe plastic wrap. Microwave on high for 4-5 minutes, or until the broccoli is tender and bright green. Once cooked, chop the florets into bite-sized pieces, ensuring they blend well into the casserole.

Step 3: Combine Ingredients
In a large mixing bowl, combine the steamed broccoli with softened cream cheese, mayonnaise, minced garlic, sharp cheddar cheese, fresh baby spinach, onion powder, salt, and black pepper. Mix thoroughly, allowing the residual heat from the broccoli to melt the cream cheese and wilt the spinach, creating a creamy, flavorful base.

Step 4: Assemble the Casserole
Spread the broccoli and spinach mixture evenly into your prepared baking dish. Once the base is laid out, generously sprinkle the shredded mozzarella cheese over the top, ensuring an even layer that will create a luscious, gooey crust when baked.

Step 5: Bake the Casserole
Place the baking dish in your preheated oven and bake for 30-35 minutes. Keep an eye on it, as the casserole is ready when the cheese is melted, golden, and bubbling. Once done, remove it from the oven and let it cool for a few minutes before serving, allowing the flavors to settle.

How to Store and Freeze Broccoli Spinach Casserole

Room Temperature: Keep leftover casserole at room temperature for no more than 2 hours to ensure safety. This duration is best for serving and short-term enjoyment.

Fridge: Store any leftovers in an airtight container for up to 3 days. Reheat individual portions in the microwave or in the oven for a delicious meal anytime.

Freezer: Freeze the casserole for up to 3 months. Wrap it tightly in plastic wrap, then aluminum foil to prevent freezer burn. Thaw in the fridge before reheating.

Reheating: Reheat in the oven at 350°F (175°C) until warmed through, about 20-25 minutes. This helps restore the creamy texture of the Broccoli Spinach Casserole, making it taste freshly made!

Make Ahead Options

These Broccoli Spinach Casserole preparations are perfect for busy weeknights! You can assemble the entire dish up to 24 hours in advance, covering it tightly with plastic wrap to keep it fresh in the refrigerator. If you want to prep even further ahead, consider freezing it for up to 3 months; just be sure to let it cool completely before wrapping tightly. When you’re ready to enjoy your casserole, simply thaw overnight in the fridge and bake at 350°F (175°C) for 35-40 minutes, or until the cheese is golden and bubbly. This way, you’ll have delicious, healthy comfort food ready with minimal last-minute effort, just as delightful as when freshly made!

Broccoli Spinach Casserole Recipe FAQs

How do I select the best broccoli and spinach for my casserole?
Absolutely! When choosing broccoli, look for bright green florets and firm stems, avoiding any with dark spots or wilting. For spinach, fresh leaves should be crisp and vibrant in color. If you can find them, organic options often have better flavor and nutrient profiles.

How should I store my leftover casserole?
Very! After serving, allow the casserole to cool and store any leftovers in an airtight container in the refrigerator for up to 3 days. This helps keep the flavors intact for your next meal. Just remember, never leave it out at room temperature for more than 2 hours to prevent spoilage.

Can I freeze the broccoli spinach casserole?
Definitely! This delicious casserole freezes beautifully for up to 3 months. To do so, wrap it tightly in plastic wrap, followed by aluminum foil. When you’re ready to enjoy it again, simply thaw it in the refrigerator overnight before reheating in the oven at 350°F until warmed through, usually about 20-25 minutes.

What should I do if my casserole turns out too watery?
No worries! If you end up with a watery casserole, this often happens from excess moisture in the spinach or broccoli. Next time, make sure to drain any thawed frozen spinach well and consider using less fresh spinach, as it wilts down considerably while cooking. You can also cook the mixture a bit longer to help evaporate some moisture.

Is this casserole suitable for people with dietary restrictions?
Certainly! The Broccoli Spinach Casserole is inherently gluten-free and low in carbs, making it suitable for many diets—including keto. However, check cheese labels for hidden gluten, and if anyone in your household has dairy allergies, you can substitute with plant-based cheese options or omit the cheese altogether!

Can I make adjustments for a personal touch?
The more the merrier! This casserole is very versatile. Feel free to add cooked chicken for protein, swap out cheeses, or incorporate different vegetables like zucchini or cauliflower. Adding spices like cumin or herbs such as tarragon can also elevate the flavor profile, making it a dish tailored to your taste!
