Ingredients Nutrition


  1. In a large frying pan, cook the onions & garlic in the butter & olive oil on medium heat for about 5 minutes. Stir in the tomatoes, ground beef, herbs, salt & pepper. Cook until the meat is browned thoroughly. Turn off heat & add egg yolk & Parmesan cheese, stirring to mix completely.
  2. Spread the meat in the bottom of a lightly oiled oven proof dish (a 9x13 would be perfect). Spread the potatoes on top of the meat mixture. And finish by sprinkling the grated cheese on top.
  3. Bake in 400 deg oven for 15 to 20 minutes, until the cheese is melted & the potatoes lightly browned.

Even though we aren't normally casserole eaters, we really enjoyed this flavorful & super easy dinner. I didn't have fresh tomatoes (I'd made a team salsa today & used them up) so I subbed a can of diced roasted garlic & onion flavored tomatoes & I left off the cheese on top as DH & DD can't eat it it (the parmesan amount was fine though). I didn't like the idea of all the grease so I browned the meat in one pan, drained it then added it to the onion, garlic, butter & oil that had been sauteeing. Thanks for a nice, quick weeknight recipe, Jackie! Made for ZWT 5 - Ali Baba's Babes. :)

AWESOME casserole! I only used one onion, but added 2 stalks of celery (great addition, I might add). I then cooked those up and added the beef, pouring off the fat when done. Then added the tomatoes and herbs (WAY more than 1 T). I added some champignons (mushrooms) which were a great addition. I then topped it off with leftover roasted garlic mashed potatoes. I topped mine off with some fresh chives. Great stuff!!! My only complaint is that the bottom of the casserole was very watery, so I just used a slotted spoon to serve. Made for a teammate for ZWT5.

This is delicious. (It's almost like a Pate Chinois, a meal we do in Quebec, with ground beef, corn and mashed potatoes, but it's not my favorite). I really like this recipe. I browned the beef and onion in a non stick skillet, without oil and butter. Then I added the tomatoes and herbs. On top, I used low-fat swiss cheese but not a lot. For the mashed potatoes, I used Garlic Herbed Mashed Potatoes (Bahama Breeze's Recipe) Thanks Jackie :) Made for the Saucy Senoritas of ZWT5
