The Not a Main Level lasagna locations in Garfield – Escape from Monday reward you for doing exactly what the level’s name suggests: ignoring the obvious route.
All three collectibles require some amount of exploration. The first sits behind an optional path near the opening wall jump, while the second asks you to ignore a directional arrow and continue straight instead. The third is easier to spot once you know where to look.
Collecting them helps unlock additional furniture for Jon’s house.
All Not a Main Level Lasagna Locations
There are three lasagnas in Not a Main Level.
Lasagna Location #1

Proceed until you reach the first wall-jump section, but do not climb it yet.
Instead, turn left.
You will find a large cheese wheel sitting on a round carpet. Keep moving left and circle around behind this area to discover a hidden path.
The jump here requires a little extra height.
Jump, perform a ground slam, then press Jump again as soon as Garfield touches the ground. If timed correctly, the bounce will launch you high enough to reach the upper ledge.
Continue left after landing.
The first Not a Main Level lasagna is waiting in this hidden area.
Lasagna Location #2

Continue through the level after collecting the first lasagna.
Eventually, you will reach an area with an arrow pointing to the right.
Ignore the arrow and keep moving straight.
Jump onto the ledge ahead, then turn left and use the wind current to cross the gap.
Continue across the trampolines, then use the next wind current to climb higher.
Once you reach the upper area, turn left.
You should see the second lasagna sitting across the gap on a wooden platform beside several pillows.
Use the nearby wind tunnel to cross over and collect it.
Lasagna Location #3

The third lasagna appears shortly after the second.
Continue until you reach the section where two tuna can platforms move toward each other.
Before leaving this area, look to your right.
You should see a blue trampoline below an upper wooden platform.
Use the trampoline to launch Garfield upward. The third Not a Main Level lasagna is sitting on top of the wooden structure.
Can You Return for Missing Lasagnas?
Yes. Once you finish Not a Main Level, you can revisit it whenever you want through Dreamland.
Your existing lasagna progress remains intact.
For example, if you collected the first and third lasagnas but missed the hidden second route, you only need to return for Lasagna Location #2 and finish the level again.
The game does not make you recollect the other two lasagnas, and you can also ignore cheese pieces you already found during your original run.
That makes Dream Land particularly useful here because most of the difficult collectibles come from optional detours rather than the main route.
