Recipe FAQs

Can I make this wild rice casserole ahead of time?

Yes, you can assemble the entire casserole ahead of time and refrigerate it before baking. When ready to serve, simply bake as directed, adding a few extra minutes if baking cold. Leftovers also reheat beautifully in the microwave or oven.

What type of wild rice works best?

True wild rice or a wild rice blend both work wonderfully. Rinse the rice thoroughly before using to remove any debris. Long-grain wild rice will have the best texture, holding up well during the hour-long baking process.

Can I substitute other vegetables?

Absolutely. Feel free to swap spinach for kale, add zucchini or butternut squash in place of bell pepper, or incorporate other vegetables you enjoy. Just keep the total vegetable quantity similar for proper baking times.

How do I know when the rice is fully cooked?

The wild rice is done when the grains are tender and have split open slightly, with most of the liquid absorbed. If needed, add a splash more broth and continue baking in 10-minute increments until tender.

Is this casserole freezer-friendly?

Yes, this freezes well. Allow the casserole to cool completely, then wrap tightly in foil and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating at 350°F until warmed through.

What can I serve with wild rice casserole?

This versatile dish works beautifully alongside roasted chicken, grilled fish, or as part of a vegetarian spread with a fresh green salad and crusty bread. It's substantial enough to stand alone as a light main course too.
