I keep coming back to this recipe whenever I need a simple breakfast dish that I know will impress and satisfy a wide array of tastes. I usually add more spices (salt, pepper, paprika, etc) but it’s a great basic recipe to start off and is incredibly tasty!
I made this using a whole small bag of potatoes O’Brien, and sharp cheddar. Very good!
Yay, glad you loved it, Susan!
This recipe is a family favorite. I’ve made it several time to rave reviews. Wondering if I can mix it up the night before and bake in the morning? Many thanks!
Hi Linda, I do not recommend it as the hash browns will get soggy and it's probably not the best food safety practice either. 🙂
But you can bake it right away, refrigerate it, and then reheat it in the preheated oven at 350 F for about 20 minutes or until hot.
Julia, just discovered your recipes! I want to make this a.m.casserole, but am a bit hesitant that the taste might be a little too subtle for our dinner club folks. Am I wrong or how can I bump up the flavor profile?
Cheers!
Hi Karen! I am so glad you discovered my site! 🙂 To add more flavor, I recommend upping the amount of chili powder. You can also use spicy pork sausage. However, if the pork sausage is too spicy, I recommend using 50% spicy / 50% regular.
Love this dish. If I only have a 9 x 13 or 8x8 dish, which is better? I actually have 2 8x8 dishes if necessary.
Leah, I would use 9x13 dish - it's exactly 3 quarts in volume just like the dish I used. 8x8 dish is 2 quarts, so if using 8x8 - use 2 of those. Enjoy and Happy Holidays! ❤️
Recipe calls for 1 pound of meat but only 6 eggs? Is that the right ratio? Doesn’t get dry?
Betty, yes, the ratio is correct. There is also 1/2 cup of heavy cream in the ingredients that adds moisture.
I just made this dish and it was delicious and cooked up perfectly! I substituted pinto beans for black beans (it’s what I had) and it was delicious. I served it with salsa and sour cream. It’s mild for those who don’t like heat, could spice it up with chilis, but i like it as is!
Lisa, thank you for your review and for sharing your feedback! ❤️ Love that you serve it with salsa and sour cream - it sounds so good!!
Do you think I could prepare this the night before and then bake it in the morning?
I really enjoyed this casserole it is definitely a keeper! For anyone interested, it freezes well. I cut it into individual sized servings and froze them for a quick breakfast on the go. I heat it up in a toaster oven as opposed to the microwave. I top it with sour cream, chives and salsa...so yummy!
Thank you for sharing this delicious recipe.
Gina, you are very welcome! And thank you so much about your helpful tips on how to freeze this.
Very Very Good. The flavors melded well. I made it a little healthier, used lean ground beef and milk. Since sausage has sodium, I did add 1/4 teaspoon of salt.
KC, thank you for this helpful feedback and 5-star review! 🙂 Glad you enjoyed this recipe!
Absolutley love this dish, I serve it with sour cream, salsa and slices of avocado. So easy to make. Can't imagine no one would like it.
Lu, I am so happy you've enjoyed this recipe! Thank you so much for stopping by and sharing such a positive comment! 🙂
Delish! One of my new go to recipes!
What temp should it be reheated at and for how long?
I would reheat it in the preheated oven at 350 F for about 20 minutes or until hot.
Can I use ham
Connie, yes, you can! Ham and black beans actually go really well together! Especially in a recipe like this.
Threw most of this away.
Just wasn't good.
It probably was the sausage we used but still I love Spanish dishes and this wasn't worth the time or expense.
I have made this several times and we, along with our guests love it. I use hot Deans sausage and serve it with salsa on the side. It is a favorite for sure.
Carmen, thank you so much for such a positive and enthusiastic comment! 🙂 I am so happy you've enjoyed this recipe and took the time to share this wonderful feedback! 🙂 Serving this with salsa on the side is delicious!
