🥘Ingredients

- fresh zucchini- it's parboiled first to soften it a bit; then chopped
- cooked rice- I prefer white long grain for this recipe, but for added nutrition, choose brown rice
- extra sharp cheddar cheese- grate this yourself for better taste and melting quality
- green onion & fresh parsley- for added flavor
- extra virgin olive oil- just a touch is used for richness
- egg- binds all the ingredients together
- dried rosemary- beautifully accents the flavors in this dish

🔪Instructions

- Step 1: Cook whole zucchini in salted, boiling water until just tender; chop when cooled; drain. Add to bowl with green onions, parsley, and cooked rice; mix.

- Step 2: Add rosemary and grated cheese.

- Step 3: Drizzle on olive oil; add slightly beaten egg; stir to combine.

- Step 4: Spread into prepared casserole dish and bake.
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
📖Variations
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.
