Ingredients
- 1 tablespoon olive oil
- 1 small yellow onion, diced
- 1 small red bell pepper, seeds removed and diced
- 1 small zucchini, diced
- 8 ounces sliced mushrooms
- 3 garlic cloves, minced
- 1/4 teaspoon dried basil
- 1/4 teaspoon dried oregano
- Dash of crushed red pepper flakes
- 8 uncooked lasagna noodles
- 1 24-ounce jar pasta sauce or homemade marinara sauce
- 1 15-ounce can diced tomatoes, undrained
- Kosher salt and black pepper to taste
- 1/2 cup ricotta cheese
- 6 ounces fresh mozzarella, thinly sliced
- 1/4 cup freshly grated Parmesan cheese
- 1/3 cup chopped fresh basil for garnish
Notes on ingredients and prep
Before you begin, make sure the skillet you plan to use has a tight-fitting lid and is large enough to hold the liquid and the noodles. A 12-inch heavy-bottomed skillet works well. Chop the onion, bell pepper, and zucchini into similar-sized pieces so they cook evenly. Slice the mushrooms and mozzarella thinly so they blend easily into the layers. The lasagna noodles are used uncooked; they’ll soften as they simmer in the sauce, so there’s no need to boil them first.
Step-by-step instructions
The following directions are written step-by-step and organized so you can follow along easily. They keep the same order as the original recipe while clarifying each action for a smooth, reliable result.
- Heat the oil and soften the aromatics. Warm 1 tablespoon olive oil in a large, lidded skillet over medium heat. When the oil shimmers, add 1 small yellow onion (diced). Sauté, stirring occasionally, for 2–3 minutes until the onion starts to become translucent.
- Add bell pepper, zucchini, and mushrooms. Add 1 small red bell pepper (seeds removed and diced), 1 small zucchini (diced), and 8 ounces sliced mushrooms to the skillet. Continue to cook for 4–5 minutes, stirring occasionally, until the vegetables begin to soften and the mushrooms release some of their liquid.
- Stir in garlic and dried herbs. Add 3 garlic cloves (minced), 1/4 teaspoon dried basil, 1/4 teaspoon dried oregano, and a dash of crushed red pepper flakes to the vegetables. Cook for 30–60 seconds, stirring constantly, until the garlic is fragrant but not browned.
- Build the tomato base. Pour in 1 24-ounce jar pasta sauce (or homemade marinara sauce) and 1 15-ounce can diced tomatoes, undrained. Stir to combine, scraping any browned bits from the bottom of the pan. Bring the mixture to a gentle simmer over medium-high heat.
- Season the sauce. Taste the sauce and season with kosher salt and black pepper to your preference. Remember that the cheeses will add salt later, so season conservatively and adjust at the end if needed.
- Add the uncooked noodles. Break the 8 uncooked lasagna noodles in half if necessary, then arrange them in the skillet in a single layer, overlapping slightly if needed. Press them into the simmering sauce so they are mostly submerged—add a splash of water if the sauce doesn’t fully cover the noodles. Reduce the heat to medium-low.
- Simmer until noodles are tender. Cover the skillet and let the noodles cook in the simmering sauce for 12–15 minutes, checking at 10 minutes to ensure the sauce remains at a gentle simmer and the noodles are softening. Stir gently once or twice, sliding the noodles around so they don’t stick to the bottom, and to help them cook evenly.
- Dot with ricotta and layer cheeses. Once the noodles are tender, remove the lid. Spoon 1/2 cup ricotta cheese in dollops across the skillet, spreading a little if needed to distribute flavor. Layer the 6 ounces fresh mozzarella (thinly sliced) evenly over the top.
- Finish under the lid until cheese melts. Sprinkle 1/4 cup freshly grated Parmesan cheese over the mozzarella. Replace the lid and let the skillet sit over low heat for 3–5 minutes, or until the cheeses are melted and bubbly. Keep an eye on it so the bottom doesn’t scorch.
- Garnish and serve. Remove the skillet from the heat. Sprinkle 1/3 cup chopped fresh basil over the top for bright, fresh flavor. Taste and adjust seasoning with additional kosher salt and black pepper if needed. Slice and serve straight from the skillet, making sure each portion gets sauce, vegetables, and plenty of melted cheese.
Serving suggestions
This Easy Skillet Vegetable Lasagna stands on its own as a full meal, but a simple side salad with a tangy vinaigrette or some garlicky roasted broccoli pairs beautifully. If you’d like a heartier plate, warm some crusty bread for dipping into the sauce. Leftovers reheat nicely in a skillet over low heat with a splash of water or in a microwave for a quicker option.
Make-ahead and storage
- To make ahead: Assemble through step 6, cover, and refrigerate for up to 24 hours. When ready to cook, bring the skillet to a simmer and continue from step 7, allowing a few extra minutes for the chilled noodles to come up to temperature.
- To store: Cool completely, then transfer leftovers to an airtight container and refrigerate for up to 4 days.
- To reheat: Rewarm portions in a skillet over low heat with a teaspoon or two of water to keep the sauce saucy, or microwave until heated through.
Tips for success
- Use a heavy skillet with a snug lid so the noodles soften evenly in the steam and sauce.
- If your sauce seems too thick to cover the noodles, stir in 1/4 to 1/2 cup water before adding the noodles. The goal is enough liquid for the pasta to absorb as it cooks.
- Thinly slice the mozzarella so it melts more quickly and distributes evenly over the noodles.
- Don’t rush the simmer—cooking the noodles gently at medium-low heat prevents them from sticking and ensures tender layers.
- Adjust crushed red pepper flakes to control the heat; a small dash adds a pleasant lift without making the dish spicy.
Variations and swaps
Want to change things up? Swap the zucchini for eggplant or add a handful of baby spinach during the last few minutes of the noodle simmer. If you prefer a creamier texture, stir the ricotta with a tablespoon of milk before dotting it over the noodles. For a nuttier finish, toast the Parmesan briefly in a dry skillet before sprinkling it on top.
Why this works
This recipe uses uncooked noodles that soften as they simmer in a generous vegetable-and-tomato sauce. That technique saves time and keeps the dish light, while layered cheeses deliver the melty texture everyone loves. A quick sauté of aromatic vegetables builds flavor from the beginning, and a short, controlled simmer ensures the noodles cook through without becoming mushy.
