Before you start
Before starting, cube the eggplant into 1-inch pieces; there is no need to salt or sweat it because the slow cooker will soften it. Mince the garlic and tear the basil. Cube the cream cheese so it melts more easily. Measure the marinara, penne, and cheeses.
If using a 6-quart slow cooker, this recipe fits perfectly; a larger one is fine, but the cooking time may be slightly shorter. Have the toasted breadcrumbs ready to go, or toast them during the last few minutes of cooking. This is a true dump-and-go meal, so all the prep is just measuring and chopping.
Ingredients at a glance (9)
- 1 medium eggplant, cubed (about 4 cups)
- 32 oz San Marzano marinara sauce
- 4 cloves garlic, minced
- 1/2 cup fresh basil, torn, plus more for serving
- 8 oz cream cheese, cubed
- 16 oz uncooked penne pasta
- 2 cups shredded whole-milk mozzarella
- 1/2 cup grated Parmigiano-Reggiano
- 1/2 cup toasted Italian breadcrumbs
Instructions
Layer and Cook
- Layer the IngredientsPlace the cubed eggplant in the bottom of a 6-quart slow cooker. Pour the marinara sauce over the eggplant. Add the minced garlic and torn basil. Scatter the cubed cream cheese over the sauce. Add the uncooked penne and stir gently to combine everything, making sure the pasta is mostly submerged in the liquid.Look for The sauce should coat the eggplant and pasta; the cream cheese pieces will look like white cubes among the red sauce.Tip Do not stir too vigorously; the penne needs to stay in contact with the liquid to cook evenly.
- Cook on LowCover the slow cooker and cook on LOW for 2.5 hours, without lifting the lid, until the penne is tender and has absorbed most of the sauce. The eggplant should be very soft and the cream cheese melted into a creamy sauce.Look for The pasta should be al dente but tender, and the sauce should be thick and creamy.Tip Resist the urge to open the lid during cooking; each lift releases heat and adds cooking time.
At the end of this phase, the slow cooker will be filled with a vibrant red sauce, with cubes of eggplant and penne visible. The cream cheese will have melted into the sauce, giving it a slightly creamy appearance. The aroma of garlic and basil will fill the kitchen.
The penne should be tender but not mushy, and the sauce should have thickened slightly. If the sauce looks too thin, cook for an additional 15 minutes with the lid off to reduce it. If the pasta is still hard, cook for another 15 minutes with the lid on.
Melt the Cheese
- Add the CheesesOnce the penne is cooked, sprinkle the shredded mozzarella evenly over the top. Then sprinkle the grated Parmigiano-Reggiano over the mozzarella. Cover the slow cooker and cook on LOW for another 15 to 20 minutes, until the cheeses are completely melted and bubbly.Look for The cheese should be fully melted and starting to brown slightly at the edges.Tip For a golden top, transfer the slow cooker insert to the broiler for 2 to 3 minutes, watching closely.
- Toast the BreadcrumbsWhile the cheese melts, place the Italian breadcrumbs in a small dry skillet over medium heat. Toast, stirring frequently, for 2 to 3 minutes, until golden and fragrant. Remove from the heat and set aside.Look for The breadcrumbs should be golden brown and smell nutty.Tip Watch carefully; breadcrumbs can go from golden to burnt very quickly.
The mozzarella and Parmigiano-Reggiano will melt into a gooey, golden layer on top of the pasta. The edges may brown slightly, creating a delicious crust. The dish will look like a bubbling casserole, and the cheese will stretch when you lift a spoonful. The smell will be intensely cheesy and comforting. Check that the cheese is fully melted and the sauce is bubbling around the edges. If the cheese is not melted after 20 minutes, cover and cook for another 5 to 10 minutes.
Finish and Serve
- Finish and ServeScoop the eggplant parmesan penne into bowls, making sure to get some of the melted cheese on top. Sprinkle each serving with toasted breadcrumbs and additional fresh basil leaves. Serve hot.Look for The pasta should be creamy, the cheese stretchy, and the breadcrumbs add a crunchy contrast.Tip Use a large spoon to get a good portion of sauce and melted cheese with each scoop.
The finished dish will have a glossy, cheesy top with golden browned spots. The toasted breadcrumbs add a crunchy, golden contrast. When you scoop into the bake, you will see the creamy sauce, tender eggplant, and perfectly cooked penne. The basil leaves add a fresh, green pop. The dish should look hearty and inviting, with a rich, tomatoey aroma. Serve immediately while hot and stretchy.
Common mistakes
One common mistake is lifting the lid during cooking, which releases heat and extends the cooking time. Trust the recipe and keep the lid on. Another is using a pasta shape that is too small or delicate, which can turn mushy; stick to sturdy shapes like penne, rigatoni, or ziti.
Overcooking can turn the pasta to mush, so check at the 2-hour mark if your slow cooker runs hot. Also, be sure to stir gently when adding the ingredients, but not too much, as that can break the pasta. Finally, do not skip the toasted breadcrumbs; they provide a crucial textural contrast that makes the dish feel complete.
How to tell it’s done
The dish is done when the penne is tender but still has a slight bite, and the sauce has thickened to a creamy consistency. The eggplant should be very soft and easily pierced with a fork. The cheese on top should be completely melted and bubbly, with a slight golden color at the edges.
If you inserted a thermometer into the center of the pasta, it should read at least 165°F (74°C) to ensure everything is heated through, though this is not a protein-based dish. Let the dish rest for a few minutes before serving so the sauce sets slightly and the cheese firms up a bit, making it easier to serve.
