🔪Instructions

- Cook whole zucchini in salted, boiling water until just tender. Chop when cooled.
- Once properly drained, place the chopped zucchini in a large bowl. Add green onions and parsley. Then add the cooked rice and gently mix.
- Next, add the rosemary and grated cheese. Gently mix.
- Drizzle on the olive oil and add the slightly beaten egg. Stir to combine.
- Place mixture in a lightly greased 13x9 glass baking dish. Spread the mixture with a spoon to evenly cover the bottom of the dish.
- Bake uncovered in a 350 degree preheated oven for 45-50 minutes, or until casserole is slightly brown around the edges and center is somewhat firm.
Hint: While the zucchini is cooking, cook the rice according to package directions, grate the cheese, chop the parsley and dice the green onions to save time.
🥣Substitutions
Rice: You may choose brown rice for added nutrition
Parsley: Dried parsley may be substituted for the fresh

Make this with yellow squash instead for a Cheesy Rice Squash Casserole. We like this version with baked ham.
Add 1-2 cups of precooked chicken before baking for added protein and taste. This makes an excellent main meal that's kid friendly.
Add chopped, crisp bacon to the top before serving for a crispy, salty crunch.

💭Top Tip
Once the zucchini is chopped, generously salt it and let it sit in a colander to drain for at least 10 minutes. Then absorb excess water with paper towels before adding it to the dish. You don't want to add overly moist zucchini to the casserole because it will make the consistency too mushy.
