Tips & Substitutions

For a spicier kick, consider using hot sausage instead of mild. You can substitute low-fat sour cream for a lighter version or Greek yogurt for a tangy twist. If you're short on time, pre-cooked sausage can be used to save cooking time. Make sure to thoroughly drain the sausage and onion mixture to avoid a soggy bottom.

Serving Suggestions

These Sausage Onion Squares are perfect for brunch and pair wonderfully with a fresh green salad or some sliced fruit. For a heartier meal, serve with a side of roasted vegetables. They also make for great game day snacks or a delicious appetizer. Consider serving alongside a light dip for added flavor.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the squares in a preheated oven at 350°F (175°C) for about 15 minutes or until heated through. You can also microwave individual squares for about 1 minute or until warm.
