I'm about to start building my outdoor kitchen and I'm trying to avoid spending a couple thousand dollars to tie it into my sewage going to the road. Has anyone successfully made a cheap, effective drain for their outdoor kitchen sink? I'm thinking about some type of French drain since it shouldn't have a ton of water at any given time. I do have clay though so I've read that it may not do well. Pics or links greatly appreciated.

my outdoor kitchen sink has a pipe that runs along the floor edge and turns the corner into my gutter drain. Gutter drain is piped underground to edge of yard.

Sorry, you're not going to like my answer but a large outdoor sink with a powerful garbage disposal that ties in the sewer line...is worth gold. I never realized how many things I would wash in that sink because I didn't want to bring them inside. Yes, it's expensive to do this due to permits and plumbers, but it's worth it if you can find the money anywhere. Splurge on that and leave some bells and whistles out now which you can add later.

We just finished our swimming pool build and went way over budget lol. I put in an extra 800 sq-ft of concrete over our original plan because you can never have too much concrete. I may do it to the sewer line but was hoping I wouldn't need to just use to rinse off food and wash hands.

Tie into a clean out connected to your plumbing-I do this often for outdoor kitchen drains.
Edit: if one is close enough to maintain gravity fall..

Is this your forever home?

If you sell, you may or may not get caught.

Also, if you are getting a permit for this, they will probably catch it and make you do it.

Seems to reason if he's thinking of doing a simple French Drain, he's not even got a single thought of getting a permit to do the work.

I helped connect an outdoor kitchen to the sewer system last year. We ran the drain to a small buried sump pump. From the sump pump, we ran a line all the way to the sewer up front using a combo on a 45 with a bushing in the combo.

How deep?
Use post-hole diggers to see if you hit sand or porous strata, say 2' to 3' below grade.
If yes make a dry well.
Dig a hole 24"-36" in diameter, preferably 3' deep.
Insert 2" PVC line about 24" vertically from the bottom of the hole.
Fill with river pebbles.
FWIW, at the last Catholic church we built, this is how the wash basin in which the Priest washes the Communion chalices and vessels are drained, for obvious reasons.
