Top and Bake
Cover with remaining squash and cheese. Bake at 375°F (190°C) until bubbly

Chef Tips for Perfect Results
- Cook spaghetti squash just until tender – overcooking leads to gummy texture
- Press meat mixture firmly after layering for better contact with milk-rice
- Cover casserole during first 15 minutes to melt cheese evenly
- Finish with fresh parsley and a spoon of ketchup for extra tang
Common Mistakes to Avoid
- Mismatched cooking times: Milk-based rice needs 12 minutes at 185°F (85°C) for perfect doneness
- Insufficient preheating: Oven must reach full temperature before adding casserole
- Underbrowning meat: Brown meat until well seared for concentrated flavor
- Adding raw vegetables: Pre-cook all squash and mushrooms to ensure even doneness
Variations and Substitutions
| Ingredient | Substitution | Impact |
|---|---|---|
| Spaghetti Squash | Zucchini noodles | Anaheim peppers add sweetness |
| Ground Beef | Italian sausage | Extremely rich and meaty |
| Velveeta | Shredded mozzarella | Less stringy but milder flavor |
