3 cuts. But I have a new way of doing it without moving the slices once the have been cut.
1st cut. Vertical. Cut the pizza in half (if it was a clock, we would be cutting it from 12 to 6). We have two slices so far.
2nd cut. Horizontal. Cut the pizza in another half (if it was a clock, we would be cutting it from 9 to 3). We have 4 slices so far.
3rd cut. Transversal. With a very sharp long knife and lots of skills, we should be cutting the with of pizza in half. This way, we would have 8 equally big slices but 4 of them would have the tomatoe and the nice stuff whereas the other 4 would only have the base of the pizza.

1 round pizza
1st CUT = 2 pcs
from 2 pcs od pizza continue to cut together
2nd CUT = 4 pcs
take out 1 pcs
from 3 pcs of pizza continue to cut together
3rd CUT = 6 pcs
6pcs + 1 pcs = 7 pcs
So with minimum 3 cuts we can get 7 pcs of pizza

All the cuts we try through will yield even number of pieces. The way to do it is as follows. The imaginary diameter of pizza is to be divided in to seven parts and effect vertical cuts. You will have seven pieces.

If the minimum number of cuts to create 8 pieces is 3, then definitely the answer is 3!! (note: you didn't say the pieces have to be of the same shape and size!)

Three , a little triangular bit is left in the middle, three pieces are triangles with an outer curved edge (assuming your pizza is round) and the other three outer pieces look like big, three straight cut sides plus a curvy side thingies.

Assuming you don't fold the pizza 3 cuts across the pizza leaving a triangle piece in the middle

4 cuts of course! the 1st cut would yeild the pizza into halfs, the 2nd would yeild the pizza into 4 equal quarters, the 3rd cut would yeild 2 quarter slices & 4 slices equal to 1/8 of the total area & the 4th & finial cut would be a cut equal to only 1/2 of the diameter which would yeild 1 slice equal to 1/4 of the total area & 6 slices equal to 1/8 the total area.
