Ingredients & Substitutions

Ingredient List

Here’s everything you’ll need:

• 1 package (11 oz) cheddar bay biscuit mix (or 8 cheddar biscuits, chopped)
• 4 large eggs
• 1 cup milk
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ¼ teaspoon salt
• ¼ teaspoon black pepper
• 1 cup shredded cheddar cheese
• 2 tablespoons melted butter
• 1 tablespoon chopped chives (optional garnish)

Optional Add-Ins:

• ½ cup chopped spinach
• ¼ cup sautéed onions or mushrooms
• ½ cup cooked vegetables like broccoli or zucchini

Notes on Quality

• Biscuits: Fresh dough is best—older dough can turn gummy or heavy
• Cheese: Shredding your own sharp cheddar gives the best flavor and melt
• Milk: Use whole milk for richness, or substitute your favorite plant-based option

Possible Substitutions

• Use gluten-free biscuit mix for a celiac-friendly version
• Replace cheddar with Monterey Jack, Gouda, or Pepper Jack
• Make it dairy-free with unsweetened oat or almond milk and dairy-free cheese
• Add herbs like thyme, parsley, or dill for extra freshness

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
2. Prepare the biscuit dough according to package directions, or use pre-made cheddar biscuits. Cut into quarters and spread evenly in the dish.
3. In a mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper.
4. Sprinkle shredded cheddar cheese evenly over the biscuit pieces.
5. Pour the egg mixture over everything, gently pressing biscuits to coat.
6. Drizzle melted butter across the top.
7. Bake for 30–35 minutes, or until the eggs are fully set and the top is golden brown.
8. Let cool for 5–10 minutes before slicing. Garnish with chopped chives and serve warm.

Best Practices

• Use room temperature eggs and milk for even mixing

Common Mistakes

• Don’t forget to grease the pan—otherwise, cleanup will be tricky
• Avoid overbaking—the center should be just set, not dry
• Spread biscuit pieces evenly so they bake uniformly

Time-Saving Tips

• Assemble the night before and refrigerate
• Use pre-shredded cheese and pre-chopped veggies
• Freeze extra portions for quick weekday breakfasts

Frequently Asked Questions

Substitutions & Adjustments

Can I use frozen biscuits?
Yes—just thaw them fully before using so they cook through properly.

How do I make it vegetarian?
This recipe is already meat-free! Just add your favorite veggies for extra bulk.

Can I double the recipe?
Yes, just use a larger baking pan or two 9×13 pans and increase bake time by 10–15 minutes.

Can I use egg whites?
You can! Substitute 8 egg whites for the 4 whole eggs—just note the texture will be lighter and less rich.

What if I don’t have cheddar bay mix?
Use regular biscuit dough and add your own shredded cheddar and a dash of garlic powder for a similar flavor.

Troubleshooting

Why is the middle still jiggly?
It probably needs more time—bake in 5-minute intervals until just set.

Why is it dry?
Overbaking can cause this. Keep an eye on it around the 30-minute mark and remove when the eggs are just set.

Why are the biscuits undercooked?
Make sure they’re fully surrounded by the egg mixture and not piled on top of one another.
