Ingredients Overview

High-protein sheet pan eggs get their protein from a simple mix of whole eggs and egg whites, poured directly into a lined pan instead of portioned into individual cups. According to the National Institutes of Health Office of Dietary Supplements, eggs are one of the richest natural sources of choline, a nutrient many people don’t get enough of from diet alone.

Diced ham, bell peppers, and spinach add flavor and color throughout, while shredded cheddar melts into every square. Every ingredient here is easy to find at a regular grocery store, so there’s no special shopping trip required.

Step-by-Step Instructions

Follow these simple steps to make your High-Protein Sheet Pan Eggs from start to finish:

1. Preheat your oven to 350°F. Line a rimmed 9×13-inch baking pan with parchment paper and grease with cooking spray.
2. Whisk together the eggs, egg whites, milk, garlic powder, salt, and pepper in a large bowl.
3. Stir in the spinach, bell peppers, ham, and shredded cheddar.
4. Pour the mixture evenly into the prepared pan.
5. Bake for 20-25 minutes, until set and lightly golden. Cool for 5 minutes, then cut into 8 squares.

💡 Pro Tip: Line your pan with parchment paper before pouring in the egg mixture, so your high-protein sheet pan eggs lift out and slice cleanly without sticking.

Meal Prep & Storage Tips

High-protein sheet pan eggs are one of the easiest breakfasts to batch, since the whole pan bakes and cools in one piece. Sealed in an airtight container, the squares keep for up to 5 days in the fridge, or up to 2 months in the freezer. Reheat in the microwave for 30-45 seconds from the fridge, or closer to 90 seconds from frozen.

If you’re prepping for the week, wrap individual squares or portion two per container so grabbing breakfast takes zero thinking on a rushed morning. Avoid the toaster oven for reheating, since it can dry out the edges.

Variations & Substitutions

Swap the ham for turkey sausage or crumbled bacon, or use kale instead of spinach for a heartier bite. Dairy-sensitive? Skip the cheddar or use a dairy-free shredded cheese alternative. For a lower-carb version, add extra vegetables like mushrooms or zucchini in place of some of the egg mixture, without changing the bake time much.

FAQ

Can I double this High-Protein Sheet Pan Eggs recipe? Yes — use two pans and bake them on separate oven racks, rotating halfway through for even cooking. It’s an easy way to stock the freezer for two weeks instead of one.

How is this different from egg muffins? High-protein sheet pan eggs bake flat in one pan and get cut into squares, while our egg muffins are portioned into individual cups before baking. Both use the same basic batter, just a different pan and a different amount of hands-on time.

Why use both whole eggs and egg whites? Egg whites boost the protein count without adding extra fat, while whole eggs keep the texture rich and the flavor balanced. According to the National Institutes of Health Office of Dietary Supplements, whole eggs also carry most of an egg’s choline, so keeping some whole eggs in the mix matters for more than just texture.

Do I need to thaw a frozen square before reheating? No, you can microwave a high-protein sheet pan eggs square straight from frozen — just add an extra 30-60 seconds to the reheating time compared to a fridge-stored one.

How many squares should I eat for breakfast? Most people find 2 squares (about 16g of protein) satisfying as a standalone breakfast — pair with fruit or toast if you want more carbs alongside it.
