This is a grain-free lasagna built with zucchini strips instead of pasta sheets, layered with a ground beef and Italian chicken sausage meat sauce and melted mozzarella. It fits a Primal eating style — no grains, full-fat dairy allowed — but honestly, it’s worth making simply because it’s a solid, filling bake that comes together faster than traditional lasagna. No boiling noodles, no waiting for pasta to hydrate.
The short version of why this works
Two things make or break this dish. First, salting the zucchini slices and letting them sit before assembly pulls out excess moisture. Skip this and the finished bake turns watery, which dilutes the sauce and makes the layers slide apart. Even ten minutes on a paper towel with a light salt helps. Second, browning the ground beef and chicken sausage properly — not just cooking through, but getting some color on the meat — builds the flavor the tomato sauce needs to taste like something. Crowd the pan and you steam the meat instead of browning it, so work in batches if your skillet is small. Both steps add maybe fifteen minutes total and they’re the difference between a tight, flavorful lasagna and a soggy one.
Substitutions that actually work
- Italian chicken sausage: If you can’t find it pre-made, use plain ground chicken with a pinch of fennel seed, red pepper flakes, and garlic powder mixed in. It gets you close.
- Zucchini: Yellow summer squash works the same way. Eggplant sliced thin is another option — it holds up well and adds a meatier texture to the layers.
- Mozzarella: Provolone melts cleanly and has a sharper flavor if you want more bite. Avoid pre-shredded bags if you can — the anti-caking coating slows melting.
- Black olives: Skip the garnish — not worth the extra dish if you’re not an olive person. The sauce is complete without them.
Troubleshooting
- Watery bake: Beyond salting the zucchini, make sure your tomato sauce simmers long enough to reduce before layering. A thin sauce plus wet zucchini is a guaranteed puddle at the bottom of the dish.
- Layers collapse when serving: Let the lasagna rest uncovered for at least 10 minutes after it comes out of the oven. Cutting into it hot means the layers haven’t had time to set.
- Cheese browns too fast before the center is hot: Cover the dish with foil for the first two-thirds of baking time, then uncover to brown the top. This keeps the cheese from burning while the interior finishes cooking.
- Meat sauce tastes flat: Tomato paste needs a minute or two of direct heat in the pan before the liquid goes in — this cooks off the raw, tinny edge. If you added it straight to the sauce, a small pinch of sugar or a splash of balsamic can rescue it.
- Ground chicken not reaching safe temperature: Ground poultry must hit 165°F (74°C) internally. If you’re unsure the meat layer is fully cooked through after assembly, use an instant-read thermometer in the center of the dish before pulling it from the oven.
Storage and reheating
Leftovers keep well in an airtight container in the fridge for up to 4 days. The zucchini softens further overnight, which most people find makes the texture even better the next day. Reheat individual portions in a skillet over medium-low with a lid on — this warms it through without making the cheese rubbery the way a microwave can. If you use the microwave, cover loosely and go in 60-second bursts. For freezing, portion into single servings before freezing; the texture holds better than freezing a whole slab. Frozen portions are good for up to 2 months. Thaw overnight in the fridge before reheating.

- Afterward, place your ground beef and sausage into the skillet until brown and cooked all the way through.
- Once the meat is cooked, pour diced tomatoes and tomato paste inside the dish with the meat and mix well.
- Use a mandolin slicer to cut your zucchini into “lasagna noodles” and lay across the bottom of a baking dish.

Frequently asked questions
Do I really need to pre-salt the zucchini, or can I skip it?
You shouldn’t skip it if you want a bake that holds together. Zucchini releases a significant amount of water during cooking, and that liquid will pool at the bottom of the dish and make the sauce thin. Even a quick 10-minute rest on salted paper towels makes a real difference.
Can I assemble this the night before and bake it the next day?
Yes, and it works well. Assemble fully, cover tightly with foil, and refrigerate overnight. Pull it out 20 minutes before baking so it’s not ice-cold going into the oven, and add 5–10 minutes to the bake time since it’s starting cold.
How do I know the meat layer is fully cooked through after baking?
Use an instant-read thermometer inserted into the center of the dish — it should read at least 165°F (74°C) because of the ground chicken sausage. Ground beef alone requires 160°F (71°C), but the higher target covers both meats safely.
Can I use a mandoline if I don’t have one — what’s the best knife technique for the zucchini?
A sharp chef’s knife and a steady hand get you there. Halve the zucchini lengthwise first so you have a flat side to rest on the board, then slice into strips about ¼ inch thick. Slightly thicker slices are fine — they just need a minute or two longer in the oven.
Is there a dairy-free version that still works?
You can leave the cheese out entirely and the meat sauce layers still make a satisfying bake — it just won’t have the classic lasagna pull. Dairy-free mozzarella-style shreds vary a lot in how they melt, so results depend heavily on the brand you choose.
