Can I use fresh broccoli instead of frozen?

Absolutely! Cut fresh broccoli into small florets and add them to the casserole as you would frozen. They might maintain a bit more texture, which many people prefer. If you like softer broccoli, you can partially steam it before adding to the casserole.

My quinoa turned out crunchy. What happened?

This usually happens when there wasn't enough liquid or the foil wasn't sealed tightly. Make sure your quinoa is fully submerged in liquid before baking and create a tight seal with the foil to trap steam. If it's still crunchy after the recommended cooking time, add a splash more hot stock, reseal, and bake for another 5-10 minutes.

Is this recipe gluten-free?

Yes! Quinoa is naturally gluten-free, as are all the other ingredients. Just double-check your stock to ensure it doesn't contain any gluten additives if you're cooking for someone with celiac disease or gluten sensitivity.

Can I make this in my Instant Pot?

Definitely! Add all ingredients (except cheese) to your Instant Pot, stir well, and cook on high pressure for 1 minute, followed by a 10-minute natural release. Stir, transfer to a baking dish, top with cheese, and broil as directed in the original recipe.

How to Make Broccoli Quinoa Casserole

Step 1: Prepare Your Aromatics

Preheat your oven to 375°F. Heat butter or oil in a saucepan over medium heat. Add your diced onion and minced garlic, cooking until they’re wonderfully soft and fragrant, about 5 minutes. This creates the flavor foundation of your casserole.

Step 2: Create Your Cooking Liquid

Add the stock, parsley, salt, and pepper to the saucepan with your aromatics. Bring the mixture to a full boil – this hot liquid will jumpstart the cooking process for your quinoa.

Step 3: Assemble the Casserole

In a 9-inch baking dish, combine your rinsed quinoa, drained chickpeas, and frozen broccoli (no need to thaw). Pour the boiling aromatic stock mixture over everything and give it a gentle stir. Make sure all quinoa is submerged in the liquid for proper cooking.

Step 4: Bake Covered

Cover the dish tightly with aluminum foil to trap steam and create the perfect cooking environment. Bake for 25 minutes in your preheated oven. After baking, let it rest for 5 minutes with the foil still on – this allows the quinoa to finish absorbing any remaining liquid.

Step 5: Add the Cheesy Topping

Preheat your broiler while the casserole is resting. Carefully remove the foil (watch for steam!) and sprinkle cheddar cheese evenly across the top of your casserole.

Step 6: Broil and Serve

Place the casserole under the broiler for 2-4 minutes, watching closely until the cheese turns golden and bubbly. Garnish with additional fresh parsley or chives for a pop of color and fresh flavor before serving.

Pro Tips for Making the Recipe

Rinse Quinoa Thoroughly: Don’t skip this step! Rinsing removes quinoa’s natural bitter coating and results in better flavor.
Stock Matters: Use a high-quality stock since it’s the primary cooking liquid and flavor base.
Even Distribution: When assembling, ensure ingredients are spread evenly throughout the dish for consistent cooking.
Tight Foil Seal: Create a tight seal with your aluminum foil to trap steam, which helps cook the quinoa perfectly.
Watch the Broiler: Keep a close eye during broiling – the difference between perfectly melted and burnt cheese happens in seconds!

How to Serve

This versatile casserole works wonderfully as both a main dish or satisfying side. Here are my favorite serving suggestions:

As a Main Dish:

Serve with a simple green salad dressed with lemon vinaigrette for a complete, balanced meal.

As a Side:

Pair with roasted chicken, grilled fish, or seared tofu steaks for a protein-forward meal.

For Brunch:

Top each portion with a perfectly fried egg for a protein-packed brunch option.

Make Ahead and Storage

Storing Leftovers

Store covered in the refrigerator for up to 4 days. The flavors actually deepen overnight, making leftovers something to look forward to!

Freezing

This casserole freezes beautifully! Portion into individual servings in airtight containers and freeze for up to 3 months. For best results, freeze before adding cheese topping.

Reheating

For refrigerated leftovers: Microwave for 2-3 minutes or reheat in a 350°F oven until warmed through (about 15 minutes).

For frozen portions: Thaw overnight in the refrigerator, then reheat in a 350°F oven for 20-25 minutes until hot. Add fresh cheese and broil if desired.
