- 1 cup diced bell peppers (red or green)
- 1 cup chopped spinach, fresh or frozen (thawed)
- cup chopped onions
- cup low-fat cottage cheese (or plain Greek yogurt)

Equipment Needed
An oven-safe casserole dish, mixing bowls, a sharp knife, and a cutting board are all you need. No special appliances are required, making this recipe very accessible to most kitchens.
Tips for Choosing Ingredients
Select fresh, organic vegetables when available to maximize nutrients and flavor. Avoid processed meats or pre-shredded cheeses with added sodium or fillers. Fresh eggs provide the best texture and fluffiness for the casserole.
Step-by-Step Instructions
Step 1 Prep Vegetables
Wash, dry, and chop the bell peppers, onions, and spinach carefully. Use a sharp knife to create evenly sized pieces, about inch cubes. No need to peel the bell peppers. Rinse spinach well to remove any grit.
Step 2 Mix Eggs and Dairy Base
In a medium bowl, whisk together the eggs and cottage cheese on medium speed for 1 minute until fully combined and smooth. This step ensures the casserole has a creamy custard-like consistency when baked.
Step 3 Combine Vegetables and Egg Mixture
Gently fold the chopped vegetables into the egg and cottage cheese base. Add salt and pepper to taste. Avoid over-mixing to maintain a light, airy texture throughout the casserole.
Step 4 Bake the Casserole
Grease a 9x13-inch casserole dish with olive oil. Pour the mixture evenly inside, smoothing the top with a spatula. Bake at 350F (175C) for exactly 40 minutes, or until the top is set and lightly golden. Remove from oven and allow to cool for 5 minutes before slicing.

Variations & Substitutions
Low-Carb and Vegan-Friendly Options
Replace eggs with flaxseed eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) or tofu for a vegan twist. Vegan cheeses or nutritional yeast can add savory notes without dairy. Try adding cauliflower rice to reduce carbs further while keeping volume.
Ingredient Swaps and Their Effects
Using powdered spices instead of fresh herbs may reduce flavor brightness. Pre-shredded cheese sometimes contains extra sodium, which may not suit your dietary goals. Fresh is always best when managing blood sugar control meals.
Adjusting Flavor with Sweetness and Spice
Add a pinch of smoked paprika or cayenne for a smoky heat. A subtle sprinkle of cinnamon balances savory flavors naturally without adding sugar. These tweaks bring warmth to the casserole without impacting blood glucose.
Storage & Shelf Life
Refrigerator Storage
Store leftovers in an airtight glass or BPA-free container. The casserole will keep fresh for 45 days. Warm gently in the microwave or oven to avoid drying out the creamy texture.
Freezer Storage
Freeze single portions wrapped tightly in foil or in freezer-safe containers. This maintains flavor and texture for up to 3 months. Thaw overnight in the fridge before reheating.
Make-Ahead Tips
Prepare double or triple batches ahead of time. Bake as usual, cool completely, slice, and freeze in portions. Label them clearly with date and contents to simplify diabetic meal planning challenges.
Pro Tips & Troubleshooting
Prevent Stains and Maximize Freshness
Wear gloves when chopping bell peppers or handling smoked paprika to avoid staining your hands and surfaces. Use the freshest eggs for optimal fluffiness and taste. Fresh veggies also brighten color and flavor dramatically.
