Ingredients you'll need
Asparagus
What to look for when buying asparagus
Look for fresh, firm, vibrant stalks. Don't buy asparagus that are limp or have wilted tips. Fresh asparagus have tips that are closed and form a point. If the points have spread or softened they are past their prime. Also avoid asparagus spears that are wider than your thumb. These can be woody and chewy.
Wash asparagus
Asparagus tips can hold sand and grit so be sure to wash them well. I like to wash asparagus by filling a baking pan with fresh water and swishing the asparagus in the water to remove any dirt that might be on the vegetable. I give the spears extra attention during the wash. Just be gentle because the tips can easily break off.
Prep asparagus
The bottom of the stalk can be fibrous and chewy. If you bought thin sticks of asparagus or very young asparagus spears, this is probably a non-issue. But if you bought thick asparagus and the ends look more like sticks of wood than food, you can just snap off the bottom inch and toss it.
Asparagus can be eaten raw, but they taste best when lightly cooked
I whipped up this egg dish in under 15 minutes with leftover asparagus. If you are starting with raw asparagus just give yourself an extra 10 minutes to roast the asparagus first. Since you can eat asparagus raw, the cook time for this tender Spring vegetable is only a few minutes.
Olive oil
Use enough good quality olive oil to roast the asparagus and keep the eggs from sticking to the pan. Feel free to use more olive oil than this recipe calls for if you prefer. It is good for your health and doesn't add to the carb count. Three tablespoons is the minimum amount.
Eggs
This recipe uses a dozen large eggs, preferably pastured eggs if you can get them.
Parmesan cheese
You can grate your own Parmesan cheese, but feel free to use grated cheese here. The cheese is to add umami flavor and help bind the eggs and asparagus together. If you are dairy-free, you can skip the cheese.
Equipment you’ll need
One 18 x 13 inch sheet pan aka baking sheet. This is a standard size baking sheet.
Serving suggestions
Omelet squares are delicious just as they are. Eat them hot or at room temperature with a fork and knife to keep it simple and keep it keto. Or feel free to add a side of salad greens, ham, bacon or sausage, or sliced smoked salmon. Enjoy it with healthy carbs by adding a side of fresh fruit or make a tartine (an open-faced sandwich) by placing a couple of squares over multigrain toast with your favorite garnish or melted Parmesan cheese.
