Step 1

Preheat oven to 350F. Grease a traditional loaf pan with nonstick cooking spray.

Step 2

Whisk together the eggs, seasonings, and ketchup before adding in the onions, mushrooms, parsley and oats. Mix until just combined.

Step 3

Then, add in ground beef and combine gently. Transfer the meatloaf mixture to the pan and gently press to ensure the top is smooth. You can brush on additional ketchup as a glaze if desired.

Step 4

Bake for about 60-75 minutes, or until the internal temperature has reached 160F. Rest 10 minutes before serving.
