Cheesy Zucchini and Squash Bake with Bacon and Tomato is what I make when the garden vegetables are piling up and I want something warmer than a salad. The zucchini and yellow squash turn soft at the edges, the tomato keeps it bright, and the bacon gives every scoop a smoky crunch.
The trick is simple. Pull some moisture from the squash before it goes into the dish, then bake covered first so the vegetables soften before the cheese browns.
Summer Pan Lineup
Use medium zucchini and yellow squash if you can. They have smaller seeds and a firmer bite than oversized squash. Ripe tomatoes are lovely here, but they should be seeded so the casserole tastes fresh without turning soupy.
- Zucchini. Gives the bake its tender green layers and mild garden flavor.
- Yellow squash. Adds a buttery sweetness and keeps the casserole colorful.
- Tomatoes. Bring acidity and juiciness that balance the cheese and bacon.
- Onion. Softens into the vegetables and gives the base a savory backbone.
- Bacon. Adds smoke, salt, and crisp bits through the layers.
- Sharp cheddar. Melts into the vegetables and gives the bake its main cheesy pull.
- Parmesan. Browns on top and adds a salty finish.
- Olive oil and butter. Help the vegetables roast and the top turn golden.
- Garlic powder and oregano. Season the vegetables evenly without overpowering the summer flavor.
Bake It Into Layers
- Heat the oven. Set the oven to 375°F and grease a 9 by 13 inch baking dish so the cheese does not weld itself to the corners.
- Salt the squash. Slice the zucchini and yellow squash into 1/4 inch rounds, toss with a little salt, and rest for 10 minutes. Blot dry with a clean towel.
- Season the vegetables. Toss the squash with tomato, onion, olive oil, garlic powder, oregano, black pepper, and a small pinch more salt.
- Build the dish. Layer half the vegetables in the baking dish. Add half the bacon, cheddar, and parmesan. Repeat with the remaining vegetables, bacon, and cheese.
- Add the butter. Drizzle melted butter over the top so the cheese browns and the edges get glossy.
- Bake and rest. Cover with foil and bake for 25 minutes. Uncover and bake 12-15 minutes more, until bubbling and golden. Rest 10 minutes before serving.
Stop The Watery Middle
Zucchini and yellow squash carry a lot of water. That is not a flaw, but it needs a little handling. A short salting step pulls moisture to the surface before baking. You are not trying to cure the vegetables. Ten minutes is enough to make a clear difference.
Tomatoes need the same thought. If they are very juicy, scoop out the seeds and loose gel before chopping. The flavor stays in the dish, but the excess liquid stays on the cutting board. The FDA has good basic advice for washing produce safely in its fresh produce guide.
Cheese That Melts Cleanly
Sharp cheddar gives this bake the big flavor people expect from a cheesy casserole. Shred it from a block if you have the extra minute. Bagged shreds work, but the coating on them can make the melt a little drier.
Parmesan is not here for stretch. It is here for salt and browning. Sprinkle some through the middle and keep a little for the top.

Smart Swaps For Dinner
This recipe is flexible as long as you protect the texture. Swap cheddar for Monterey Jack, smoked gouda, or pepper jack. Use cherry tomatoes cut in half when larger tomatoes are pale. Turkey bacon works, but cook it until crisp before layering so it does not disappear into the vegetables.
If you want a meatless version, skip the bacon and add 1/2 teaspoon smoked paprika with the oregano. You can also fold in cooked chicken and serve it as a main dish.

Storage Without Sogginess
Let the bake cool before storing it. Trapping steam in a sealed container while it is still hot makes the top wetter. Leftovers keep well in the fridge for up to 4 days. The USDA gives practical timing and reheating basics in its leftovers food-safety guide.
For the best reheat, use an oven or toaster oven at 350°F until hot. Leave it uncovered for the last few minutes. The microwave is fine when you are hungry now, but the bacon will soften.
Ways To Serve It
This bake is a strong side for grilled chicken, pork chops, steak, or burgers. It also works as a light dinner with a green salad and crusty bread. The vegetables are tender, the cheese is rich, and the bacon keeps it from tasting too polite.
If you are taking it to a potluck, bake it in a dish that can go straight to the table. Resting matters more than you think. Ten minutes gives the cheese time to settle, so each scoop lands on the plate with vegetables and bacon in every bite.
Summary
This cheesy vegetable bake works as a sturdy side dish, a light dinner with salad, or a make-ahead casserole for summer gatherings.
FAQs
- How do I keep zucchini and squash bake from getting watery?
Slice the squash evenly, salt it lightly, and let it sit for about 10 minutes. Blot away the moisture before layering. Seeding juicy tomatoes also helps the bake set instead of swimming in liquid.
- Can I make this without bacon?
Yes. Leave out the bacon for a vegetarian version and add a little smoked paprika or extra parmesan for savory depth. You can also use plant-based bacon, but add it near the top so it stays crisp.
- Can I use only zucchini or only yellow squash?
Yes. Use all zucchini or all yellow squash in the same amount. The color changes, but the bake will cook the same as long as the slices are about 1/4 inch thick.
- What cheese melts best in this casserole?
Freshly shredded sharp cheddar melts smoothly and gives the bake a bold flavor. Parmesan adds salty browning on top. Mozzarella works too, but it is milder and can make the casserole softer.
- Can I assemble it ahead of time?
You can slice and blot the vegetables, cook the bacon, and shred the cheese a day ahead. For the best texture, assemble right before baking. Fully assembled raw zucchini can release water as it sits.
- How long do leftovers keep?
Keep leftovers in an airtight container in the fridge for up to 4 days. Reheat uncovered in a 350°F oven until hot so the top can firm back up. The microwave works for a quick lunch, but the cheese will soften more.
- What should I serve with this zucchini squash bake?
It is rich enough to sit next to grilled chicken, pork chops, burgers, or eggs for brunch. For a lighter plate, serve it with a crisp green salad and a simple vinaigrette.
