Since earlier this fall, I’ve gotten back into the habit of cooking a leisurely breakfast at the weekend. Do any of you cook breakfast at the weekends? I have been making some favourites like my Old Fashioned Pancakes, Breakfast Tacos and the Apple Danish. I’ve also been trying out a few new dishes like this Croissant Breakfast Casserole. It was delicious! Try it out soon and file it in favourites for the upcoming holiday season!

What Is This Breakfast Casserole Like

• Difficulty – This is such an easy breakfast! The prep time is under 10 minutes, and you can prepare it up to the night before baking!
• Taste – If you love the texture of French Toast, you will love this breakfast casserole. It has a creamy decadent texture with pops cheese and ham.
• Serving – This breakfast will serve between 6 – 8 servings. You can adjust the serving size in the recipe card at the end of the post.

Ingredients

• Milk – I used whole milk for this baked casserole dish.
• Heavy cream – A small amount of heavy cream or whipping cream added to the mixture gives it a more decadent and rich flavour.
• Eggs – Use large eggs for this recipe. Eggs are added to the mixture to create a french toast style batter.
• Chives – Fresh chives add such a wonderful flavour to this breakfast casserole. Don’t skip the chives for the fantastic flavour.
• Croissants – I used day old mini croissants and they work perfect.
• Ham – I used thick cut smoked deli ham for this recipe. Any ham will work!
• Swiss cheese – I bought deli sliced Swiss cheese. I cut mine into small pieces. You can easily use a block of Swiss cheese and cut it into small pieces.
• Parmesan cheese – I sprinkled fresh grated parmesan cheese over the entire casserole before baking. A delicious way to finish the dish.

NOTE, The full recipe and ingredient list can be found at the end of the post in the recipe card.

Instructions

1. Preheat oven – Preheat oven to 350ºF/180ºC and have ready an 8 inch deep sided casserole dish.
2. Combine milk, cream and eggs – In a large bowl combine the milk, heavy cream, eggs and chives. Whisk really well to combine and set aside.
3. Assemble the casserole – Place the croissant pieces in the casserole dish. Scatter the ham and cheese pieces evenly between the croissant pieces. Pour over the egg mixture and make sure all the pieces are completely coated. Sprinkle the parmesan cheese over the top.
4. Bake – Cover the casserole with foil and bake between 25 – 35 minutes until completely cooked through and bubbly. Remove the foil and bake for a further 5 minutes.
5. Serve – Remove from oven and serve hot or even at room temperature.

Recipe Tips

• Make ahead – Yes, you can prep this the night before! Just cover it and keep it in the fridge until you are ready to bake in the morning.
• Keep it covered – It’s important to keep this breakfast casserole covered while baking. Otherwise it will dry out and the top will most likely brown too quickly. Just take the foil off for about 5 minutes at the end. If you want a real crisp top, just put it under the broiler for a few minutes.

Substitutions

• Mini croissants – I used small croissants but you could easily use large croissants. Alternatively, brioche bread would also work great for this recipe.
• Ham – Any kind of deli ham will work for this recipe. I used thick cut smoked ham and just cut it into small pieces. You can use thin slices for even a thick piece cut small. Deli turkey is also a great alternative.
• Swiss cheese – You can use any cheese you like. A few to try are cheddar, Havarti and mozzarella just to name a few.

Serving

This casserole is perfect without any sides or other dishes on the side. It really is a complete meal to start you weekend morning. However, it’s great to serve as part of a bigger Holiday or weekend brunch. Below I’ll share a few dishes that I would easily serve with this Croissant Breakfast Casserole!

• Almond Granola served on the table with plain Greek yogurt and milk on the side.
• Mixed Berry Muffins are great served as a sweet component for a brunch.
• Blueberry Scones would go great with Lemon Curd.
• Citrus Salad with a Honey Lime Dressing makes a great centerpiece for a holiday brunch.
