Why We Love Bisquick Breakfast Casserole

1. An easy, one-pot meal.

This recipe doesn’t require a lot of time or dishes. In less than an hour you can have bubbly, cheesy baked eggs that the whole family will love without a ton of clean-up.

2. Hearty and delicious.

We love how the flavors in this dish come together as the casserole bakes. The blend of peppers, chorizo, and egg will keep you coming back for seconds.

Ingredient Notes and Substitutions

• Ground pork chorizo
  Mexican chorizo has a smoky, mildly spicy flavor. If you can’t find pork chorizo at your local grocery store, swap it out for beef chorizo or ground breakfast sausage.
• Rotel
  This is a brand of canned tomatoes with green chilis. We use the mild variety, but you can make this Tex-Mex casserole spicier by using hot Rotel.

  If you can’t find it, make your own by combining one 15-ounce can of diced tomatoes and one 4 ounce can of diced green chilis or jalapenos.

• Mexican blend cheese
  Feel free to swap out the Mexican blend for another shredded cheese of your choice.
• Shredded potatoes/hash browns
  When you go shopping, look for refrigerated shredded potatoes. Those are our favorite, because they taste fresher, and they’re ready to use. If you can’t find them, no worries; just buy frozen hash browns and be sure to thaw them first.

Note:
If you have a dairy allergy or intolerance, this breakfast casserole with cheese and milk probably isn’t the best choice for you. Fortunately, this dairy free egg bake is one you can enjoy!

Tips and Notes For a Perfect Bisquick Casserole

1. Grease the baking dish.
   Use some butter, oil, or nonstick cooking spray to keep the egg bake from sticking.

2. Use a spatula to break the chorizo into small chunks.
   Breaking your chorizo into smaller pieces will help it to cook more quickly and evenly.

3. Don’t overmix the batter.
   It is okay to have a few clumps of Bisquick in the batter of the breakfast casserole. They’ll disappear as the egg bake is in the oven. Whisk the baking mix into the eggs, just until combined.

4. Use freshly shredded cheese.
   For the best flavor and better meltability, buy blocks of cheese and shred them yourself.

   Doing this will save you a little money, and freshly shredded cheese melts much better. This is because packaged shreds include an anti-caking agent to prevent clumping. That chemical can sometimes prevent the cheese from melting well.

5. Remember to let your Bisquick egg bake cool.
   Let the egg and sausage casserole rest for 5-10 minutes before you serve. This gives the liquid time to absorb, so you’ll have cleaner slices.

Easy Egg Bake Variations

• Use different seasonings. If you aren’t a fan of Mexican or Tex-Mex flavors, go wild with Greek spices. Another tasty option is to use Italian seasoning and shredded Mozzarella .
  
• For a gluten-free Tex Mex casserole, make our recipe the same way, but use gluten free Bisquick instead.
  
• Get creative with add-ins. Mushrooms, yellow onion, baby spinach, olives, and ricotta cheese are all great additions to this dish.

A great brunch idea is to include a side of Instant Pot black beans. The beans taste fabulous with the flavors of this Tex Mex casserole!
