Step‑by‑Step Cooking Directions
- Season & par‑cook the rice. In a small saucepan stir olive oil, salt, pepper, paprika, and oregano over medium heat until fragrant, 30 sec. Pour in rice; toss to coat grains. Add 2 cups water, bring to a boil, reduce to low, cover, and simmer 8 min—rice should absorb liquid but remain al dente. Set aside.
- Wilt the spinach. Melt butter in a large skillet over medium heat. Add chopped spinach; cook 2 min until barely wilted. Stir in grated garlic; cook 30 sec. Transfer mixture to a mixing bowl.
- Build meat‑vegetable filling. Heat olive oil in same skillet. Sauté onion 2 min until translucent. Add grated carrot; cook 2 min. Crumble ground beef into pan; season with salt, pepper, oregano, and paprika. Cook 5–7 min until browned. Fold in peas and diced red pepper; cook 1 min. Off heat; scrape mixture into bowl with spinach. Toss to combine and cool slightly.
- Whisk custard. Beat eggs until frothy. Add cream, rice flour, baking powder, salt, pepper, oregano, and paprika; whisk smooth.
- Grease baking dishes. Brush three 5×5‑inch dishes (or one 9×13) with olive oil, including sides.
- Layer casserole. Spoon a thin layer of rice into each dish, packing gently. Top with half of meat‑spinach mixture. Repeat rice and filling once more, finishing flush with rim.
- Add custard & cheese. Pour egg‑cream evenly over casseroles, letting it seep down. Sprinkle grated cheese over tops. Arrange tomato slices if using.
- Bake. Place dishes on a sheet tray. Bake in pre‑heated 180 °C / 360 °F oven 30–40 min (larger pan 40 min) until puffed, golden, and a knife inserted at centre comes out clean.
- Rest & serve. Cool 10 min for layers to set. Slice or scoop servings; garnish with extra paprika or herbs.
