Mediterranean Barley & Brown Rice Bake

Brown rice and pearl barley cooked together create a chewy, nutty base that’s heartier than either grain on its own. Layered with crisp-tender zucchini, onions, and green pepper, then baked under a basil-tomato sauce and melted mozzarella, this casserole is a vegetarian main that actually fills you up.

The grains simmer together for forty minutes, which works because brown rice and pearl barley have nearly identical cook times. Both absorb the water completely, leaving you with a fluffy, tender base that spreads into the baking dish as the bottom layer.

The vegetables get just a quick two-to-three minute blanch before layering. They should still have snap. The oven time finishes them to tender while the tomato sauce seeps down through the layers and the mozzarella melts on top.

That tomato sauce is lean and simple. Tomato paste, water, garlic, basil, and a pinch of sugar for balance. No oil, no cream. Fresh tomato slices arranged on top before baking add bright acidity and a pretty presentation under the cheese.

Kitchen Tips

• Rinse the grains before cooking. This removes surface starch that can make the base gummy instead of fluffy.
• Don’t overcook the vegetables in the blanch. Two minutes is enough. They cook more in the oven and you want them to still have texture in the finished dish.
• Cover the baking dish for the first 25 minutes. This steams everything through. The last 5 minutes uncovered with cheese lets it brown and bubble.
• Use part-skim mozzarella. It melts just as well as whole milk but keeps the dish lighter.

Variations

• Add white beans: Scatter a drained can of cannellini beans over the grain layer for extra protein.
• Greek-style: Swap the mozzarella for crumbled feta and add sliced kalamata olives with the vegetables.
