This egg casserole is a recipe that I saw in a magazine so many years ago. I don't even remember what magazine it was from.

It was such a hit that it's now a tradition. But there's no reason why we you can't make it throughout the year for a special breakfast or brunch.

🤔 FAQs

Here are the questions I am most frequently asked about Smoked Salmon Breakfast Casserole.

What is the difference between smoked salmon and lox?

Smoked salmon is cured or brined, then smoked. Lox is cured, but not smoked.

What if I don't like salmon, can I substitute for it in the breakfast casserole?

Yes. You can add cooked sausage or bacon instead. Instead of the dill add fresh basil and Italian parsley. Top with a bit of green onions.

Can I halve the recipe?

Yes you can. Along with halving the ingredients be sure Jut be to use a smaller baking dish.

📞 Chiacchierata

We started making this breakfast egg casserole when our children were very young. As the years passed, our children had children of their own. Each family wanted to be home on Christmas morning. They wanted their children to open the gifts under the Christmas tree. So, we had our family Christmas on Christmas eve, there wasn't any need to make the smoked salmon dish anymore. 

But. . . I was wrong!

The family decided to add on to their tradition. Nonna and Papa, that's us, would visit where our children lived. We’d celebrate Christmas Eve as a big family. On Christmas morning, we’d enjoy brunch together.

The Smoked Salmon Breakfast recipe was revived. 

We weren't sure how the grandsons would take to smoked salmon. To say they liked it would be an understatement. The dish was wiped clean. It's such an amazing brunch dish . It's excellent any time of year.

Along with the egg casserole, make some homemade muffins ahead of time. Try our Banana Chocolate Chip Muffins or if you're going for something lighter, our Oatmeal Apple breakfast muffins. If pancakes are more your family's breakfast treat, try our amazing Fluffy Banana Pumpkin Pancakes. You'll get lots of hugs and kisses!

If you're planning a brunch and are uncertain what to prepare, try our Italian Sausage Breakfast Strata. Layers of Italian sausage, bread, cheese, and eggs come together beautifully in this breakfast strata.

And if you love smoked salmon as much as we do, you've got to try out our delicious Pasta with Smoked Salmon in a cream Sauce.

 I don't believe where the time has gone. Days just fly by don't they?

There is a saying in Italian: Non ci ricordiamo dei giorni, ci ricordiamo dei momenti -- We do not remember days, we remember moments. That is so true when is comes to special moments with friends and family.

And for special days, and breakfasts, WOW your family and guests with this amazing make ahead Brioche French Toast Casserole. This is a special treat they'll remember for a long time.

Enjoy and savor each moment.
