How This Nutrition Estimate Was Prepared
- Every ingredient is assigned a specific gram weight instead of relying only on a cup, spoon, or item count.
- Standard unbranded food-composition values are aligned with the closest matching foods in USDA FoodData Central.
- Ingredient values are added for the full recipe, divided by the listed yield, and rounded only for display.
- Optional ingredients are excluded unless a measured amount is included in the base recipe.
Accuracy note: These numbers are credible estimates, not laboratory analysis. Weigh ingredients and calculate from the labels on the exact brands you use when precision is important.

Professional Step-by-Step Preparation
Equipment
Large cutting board, chef knife, measuring cups and spoons, mixing bowls, and the skillet, saucepan, sheet pan, baking dish, or air fryer required by the steps below.
Before You Start
Wash produce, keep raw animal proteins separate from ready-to-eat ingredients, and use a clean food thermometer when the recipe includes meat, poultry, seafood, or eggs.
Prepare the baking dish
Heat the oven to 375°F (190°C). Lightly coat a 9-by-13-inch baking dish with part of the measured olive oil.
Success tip: Keep the measured ingredient amounts consistent if you want the displayed nutrition estimate to remain comparable.
Cook the vegetables
Warm the remaining oil in a skillet over medium heat. Cook onion and bell pepper for 4 to 5 minutes, then add spinach until just wilted.
Success tip: Keep the measured ingredient amounts consistent if you want the displayed nutrition estimate to remain comparable.
Blend the protein-rich base
Whisk eggs and egg whites. Stir in cottage cheese, Italian seasoning, and black pepper until evenly distributed.
Success tip: Keep the measured ingredient amounts consistent if you want the displayed nutrition estimate to remain comparable.
Assemble the casserole
Spread the cooked vegetables and tomatoes in the baking dish, pour over the egg mixture, and sprinkle mozzarella evenly on top.
Success tip: Keep the measured ingredient amounts consistent if you want the displayed nutrition estimate to remain comparable.
Bake safely
Bake for 28 to 35 minutes, until the center is set and an instant-read thermometer reaches 160°F (71°C).
Success tip: Keep the measured ingredient amounts consistent if you want the displayed nutrition estimate to remain comparable.
Rest and portion
Rest for 8 to 10 minutes before cutting into 6 portions so the casserole slices cleanly.
