Croque Madame Muffins

I thought these were quite good and the cheese sauce much easier to make than expected. I did use the option of Parmesan instead of Gruyère since I had it on hand and didn’t want to make a trip to the store just to get another cheese. I’m sure they’d be just as delicious with Gruyère and next time I have some on hand I’ll try them that way too. I don’t buy small eggs, though I did have some that were supposed to be large but looked on the small side, so I used those. I took the muffins out of the oven after 15 minutes and they were almost perfect for my taste. The white was just a little underdone, so I left them baking for 5 more minutes. After the extra 5, there was one spot in the yolk that was a little more cooked than I prefer. I like my white done but yolks very runny. Hubby on the other hand likes his yolks completely done so I cooked his for 25 minutes. I baked these in a silicone muffin pan and they came out perfectly by scooping them with an oversized serving spoon.I think 2 muffins per person is the perfect serving size unless you serve them with fruit; then I think 1 per person would be fine.
