This Eggplant Italian Sausage Gratin is bursting with fabulous Italian flavor. A delicious, make-ahead, dinner party-worthy meal!
The first time I made this Eggplant Italian Sausage Gratin, Scott announced, after taking the first bite, "This might be the most delicious meal you've ever made!". The good thing is that I enjoy it as much as he does and it's gotten rave reviews from family, friends... everyone who tries it!

I love that this Eggplant Italian Sausage Gratin can be made hours (or even a day) in advance and simply popped in the oven for the final baking just before dinner, making it perfect for a dinner party. It's also a great dish to take to a friend or family in need; delicious comfort food that can be delivered and then baked whenever it's convenient for their schedule. I took a pan of it to a friend one evening and got this text a few hours later:
Chris, our dinner was AWESOME! We both moaned throughout the entire meal. I'm not kidding!!

I love having treasures like this Eggplant Italian Sausage Gratin in my recipe arsenal!

Although this dish might be a little indulgent for the diet-conscious, it doesn't need pasta to be enjoyed, which saves in the calorie department. Also, the recipe calls for just twelve ounces of Italian sausage which is drained of extra fat after cooking. The sausage gives tons of fabulous flavor without adding a lot of fat.
And for another healthy alternative, I decided to roast my eggplant in the oven in lieu of frying it as many eggplant recipes call for. The thick slices of eggplant are brushed lightly with olive oil, sprinkled with salt and pepper, and into the oven they go. Thirty minutes later they're tender and ready to be combined with the fragrant tomato sauce.

There's one delicious splurge that takes this Eggplant Italian Sausage Gratin over the top (literally!). While the eggplant is roasting and the tomato sauce simmers, you'll make the topping sauce. It's a simple combination of reduced heavy cream and a generous handful of both Parmesan cheese and mozzarella cheeses. The cheeses melt into the thickened cream creating a silky and incredibly flavorful gratin topping.
Once the eggplant is roasted and the sauces are ready, it's easy to put the whole thing together. Just layer the eggplant and tomato sauce in a gratin or casserole dish. Top with the luscious cheese sauce and pop the whole thing in the oven till it's bubbly and golden. Serve in shallow bowls with some crusty bread (to mop up the fabulous sauce!) and a simple green salad.

It will be a meal to remember!
Buying and cooking eggplant
- When purchasing eggplants, look for ones with smooth, shiny, taut skin that are uniform in color and heavy for their size. Small and medium-size eggplants tend to be less bitter and their skin is thin and tender. Pass by the ones that have bruising and tan patches.
- Eggplants will keep well for several days in the refrigerator.
- Eggplant is also called aubergine and is part of the nightshade family. Potatoes and tomatoes also belong to this grouping of vegetables. There have been some claims that raw eggplant is poisonous. Raw eggplant does contain the toxin, solanine. It's generally not harmful when eaten in reasonable amounts, although some people can be sensitive to it and experience gastrointestinal discomfort.
- Eggplant is high in fiber and a good source of vitamin B1, copper, manganese, vitamin B6, niacin, potassium, folate and vitamin K.
- When cooking eggplant, it has a tendency to absorb a lot of fat. That's why in the instructions, I write to "brush tops of eggplant slices lightly and quickly with olive oil." If you linger, while brushing the slices will "suck in" as much oil as they can. It's pretty crazy!

Want to plan a special meal that everyone will love? This Eggplant Italian Sausage Gratin will bring LOTS of rave reviews, sighs and probably a few moans of delight!

Café Tips for making this Eggplant Italian Sausage Gratin
- The perfect pan to cook and present this dish is an au gratin pan. Au gratin pans can be round, oval or rectangular and are usually about an inch and a half to two inches deep. They come in enamel cast iron, stainless steel, copper, ceramic or glass. There are lots of options. If you don't have an au gratin pan, no problem, you can make this dish in a cast iron or stainless steel oven-safe skillet or a casserole dish. Just make sure it's not too deep.
- Thid Eggplant Italian Sausage Gratin recipe calls for fire-roasted tomatoes. These can be found at most larger grocery stores with the other canned tomatoes. They have a wonderful flavor and a deep red color. If you can't find fire-roasted tomatoes, regular diced canned tomatoes will be fine.
- Leftovers are delicious. They can be warmed up in the oven or in the microwave. The flavors almost get better, if that's possible!
- I love to serve these Artisan Dinner Rolls, this Ridiculously Easy Focaccia Bread or our No Knead Pull-Apart Brioche Bread with our eggplant gratin. The rolls and both breads can be made ahead and frozen. Take them out of the freezer a few hours before dinner and warm in a 300˚F oven for 10-15 minutes. They're perfect to sop up the wonderful sauce, no butter needed!
- Be sure to drain any excess grease after cooking the Italian sausage. Italian sausage can vary greatly in fat content. Sometimes there will be minimal grease after cooking and sometimes you'll find you have to drain a lot off. I just tip my pan to one side, push the sausage to the high size and let the grease drain down. Then I remove it with a spoon, a turkey baster or with crumpled paper towels.
- Give the gratin 15 minutes to sit after baking and before serving. The juices will thicken a bit, helping the gratin to hold its shape better when served/
Thought for the day:
Though the fig tree does not bud
and there are no grapes on the vine.
Though the olive crop fails
and the fields produce no crops.
Though there are no sheep in the pen
and no cattle in the stalls,
yet I will rejoice in the Lord,
I will be joyful in God my Savior.
Habakuk 3:17-18

This Eggplant and Italian Sausage Gratin is bursting with delicious, universally beloved Italian flavor. It's a dinner party worthy meal that can be made in advance and just popped in the oven at the last minute!

- 2 medium eggplant sliced in ½-inch thick rounds
- 3 tablespoons extra virgin olive oil
- 1 teaspoon kosher salt
- 12 ounces Italian sausage removed from casings
- 1 tablespoon Italian seasoning
- 3 cloves garlic finely minced
- 3 14 ½- ounce can fire-roasted canned tomatoes
- ½ cup fresh basil, coarsely chopped
- 1 cup heavy cream
- 3 ounces grated parmesan cheese
- 4 ounces fresh mozzarella
-
Preheat oven to 400˚F. Line two sheet pans with foil for easy cleanup. Brush foil generously with extra virgin olive oil. Arrange eggplant slices in even layers on prepared pans. Brush tops of eggplant slices lightly and quickly with olive oil. Work quickly as eggplant likes to absorb lots of oil. You just want to lightly coat the surface. Sprinkle lightly with salt and freshly ground black pepper.
-
Bake for 15 minutes, then rotate pans and bake another 20 minutes. Remove from oven and set aside
-
While eggplant is roasting, make the meat sauce and parmesan sauce. For the meat sauce, heat a medium-large pot or Dutch oven over medium heat. Add Italian sausage and cook until lightly browned. Break the sausage up with a metal spatula and stir occasionally, as it cooks.
-
Drain excess grease and reduce heat to low. Add Italian seasoning and garlic and cook, stirring continually for 2 more minutes to soften the garlic and let the spices bloom.
-
Add fire-roasted tomatoes to the pot and increase heat to high. Bring to a boil, then reduce heat to maintain a steady simmer. Cook for 20-25 minutes, until sauce begins to thicken, stirring occasionally. Add fresh basil and cook for 5 minutes longer. Remove from heat.
-
For the parmesan sauce, pour 1 cup heavy cream into a medium-size saucepan. Heat over medium heat until simmering. Reduce heat and continue to cook, maintaining a medium-low simmer, until reduced approximately in half. This will take about 10 minutes. Add Parmesan and mozzarella. Stir over low heat, until cheese is melted and sauce is smooth. Cover and set aside.
-
To assemble gratin, lightly grease a low enameled cast iron pan, gratin pan or low casserole. Arrange half of the eggplant in the pan. Spoon about ½ of the meat sauce over the eggplant and then repeat layers.
-
Stir the Parmesan sauce well and pour over the top of the eggplant and sauce. You can leave some of the eggplant mixture showing, if desired.
-
Reduce temperature to 350˚F and bake gratin until bubbly and beginning to turn golden in spots, 25-30 minutes. Remove from oven and allow to sit for 10 minutes before serving. Serve in shallow bowls with crusty bread.

Sue says
Hi Chris. We love so many of your recipes! A question about this one is can I make it without sausage (not a fan)? Maybe substitute ground beef or just leave the meat out altogether? Thanks
Chris Scheuer says
Hi Sue, thanks for your kind words.
Regarding your question, yes, you could make this with ground beef or without any meat.
Pam says
Very difficult recipe to follow given all the pop up ads. But even after persevering only average recipe. Lots of other superior eggplant Parmesan recipes out there with no annoying ads.

My friend made this for me while I was recovering from surgery and it was sooo delicious. She gave me the recipe and I plan on making it soon. My question is what size au gratin pan does this recipe call for?
Chris Scheuer says
Hi, my pan holds 2 quarts.
Kerry Deal says
This is my fourth time making this recipe so I thought I should leave a review! Absolutely delicious every time (and one time I made it with Impossible Sausage for vegetarian guests). I usually serve over pasta, and get some leftovers out of it.
Lindsay @ The Café Sucre Farine says
Awesome! Thank you for letting us know, Kerry!
Robin Cichy says
I made this with four small eggplant which I had just picked from the garden. I also didn’t have mild Italian sausage, so I use the hot Italian sausage. This recipe is a winner! It looked beautiful and tasted even better. The heavy cream and the cheese sauce makes all the difference and is worth taking the time to make it.
Lindsay @ The Café Sucre Farine says
Awesome! Thanks for your review, Robin!
JoAnn says
I made this last night for a dinner party. It was outrageously delicious. My dinner guests raved about it. What a beautiful presentation, as well. I placed pasta on an indivual plate and spooned the eggplant sausage casserole over it. It was a hearty and very satisfying meal. I will be making this over and over again. Thank you for such a wonderful recipe!
Lindsay @ The Café Sucre Farine says
Thanks so much for your review, JoAnn! So glad you enjoyed this recipe!
Chris Scheuer says
Hi Nanci, you could definitely use the Japanese eggplant and ground sausage is great!
Nanci says
Wanting to make this but 2 questions: can I use the small Japanese eggplant? and the ground Italian sausage, or is best to buy and use the ones in casings? Thanks
