A Mexican Frittata – Chile Relleno Casserole

This entry is part 76 of 76 in the series Gluten-Free

Traditional chile rellenos are usually made with poblano peppers that have been seeded and stuffed with cheese. Then they are dipped in a batter and fried until crispy. You cut into them and the hot, melted cheese blends with the crunchy exterior and rich flavor of the peppers creating the perfect bite.

The Artist loves chile rellenos, but is rarely satisfied when he orders it at Mexican restaurants. It is one of those dishes that is remarkably easy to screw up and it takes a delicate hand to make correctly. This casserole is a lovely adaptation of the classic, creating a much easier way to serve this delicious meal.

Setting multiple dishes on a baking sheet makes them easy to move around

The traditional version does not contain meat, but in order to make this a heartier dish, I added a seasoned meat layer on the bottom of the dish. This meat mixture is held together with beaten eggs giving the illusion of the flavors of chile rellenos. If you don’t want to use beef, you could replace it with turkey, pork, cooked rice, potatoes or any combination of vegetables.

After the egg mixture has been added; ready for the oven!

I thought it would be fun to make this in au gratin dishes. Not certain if it would rise as it cooked, I divided the meat mixture between three dishes. It turns out that I could have put it in two, filling them about 3/4 or more full. Mine came out fairly thin, so we each ate an entire au gratin of the dish.

Hot from the oven

The egg mixture doesn’t take up much room in the baking dish, but it acts as a binder to hold all the other ingredients together. Bake this casserole until the eggs are solid and the top is nicely browned. Your oven will very likely differ from mine, so always use timings as an estimate. If you over bake it, the eggs will get rubbery, so it is better to pull it a little early and then let it finish firming from the carry over cooking up as it rests.

The Artist commented that this would make a great breakfast or brunch dish and I agree. I might add some sausage to the meat mixture for a little more typical breakfast/brunch flavor profile, but it would certainly be popular on a buffet!

If you wanted, you could make the meat layer a day ahead, cover and refrigerate. Then 20 minutes before you are ready to bake it, bring it out, pour the eggs over the top and pop in the oven for an easy, hands-off breakfast, brunch, lunch, or dinner!

We loved this dinner and the leftovers will be even better. I know what I’m having for lunch tomorrow, how about you?

Jane’s Tips and Hints:

Make sure you break up the hamburger really well. Large chunks will not hold together well. A little extra attention when the beef is browning and you’ll have a much more attractive and easier to eat dinner!

If you decide to use more than a single baking pan, place them on a baking sheet – they are much easier to move in and out of the oven!
