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.

  1. 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.
  1. 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.

  1. 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.

  1. 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.

Equipment

  • 13" x 9" baking dish - or a 3-quart, shallow, oven-safe casserole dish

  • 10" – 12" skillet

  • medium bowl

Ingredients

  • 1 pound ground chorizo
  • 1 large bell pepper any color, diced
  • 10 ounces mild Rotel tomatoes drained *See Notes for substitutes

Instructions

  • Preheat oven to 400ºF.

    Prepare a 3-quart baking dish by spraying with non-stick cooking spray. Set aside.

  • In a large skillet over medium-high heat, cook ground chorizo for 7-8 minutes, until browned. Carefully drain fat from pan, then transfer the chorizo back to the oven-safe skillet, or to a baking dish.

  • To the cooked chorizo, add diced bell pepper, drained Rotel, thawed hash browns, 1 cup shredded cheese, and 1/4 cup sliced green onions to the casserole dish and mix together.

  • In a medium mixing bowl, whisk together eggs and milk until well-blended. Stir in the Bisquick until mixed. Pour over the chorizo vegetable mixture. Top with 1 cup of shredded cheese.

  • Let cool for at least 10 minutes before serving. Garnish with remaining 1/4 cup of green onions and chopped tomato (optional) before serving.

Notes

  • Rotel – This is a brand of diced tomatoes with green chiles. If a substitute is needed, combine 3/4 cup canned diced tomatoes (drained), plus 1/4 cup diced green chiles.
  • Shredded Mexican Cheese – For the best meltability and flavor, shred a block of cheese yourself. Colby Jack, Monterey Jack, and Pepper Jack are good substitutes.
