If both parties knew a contract was illegal, can either one still recover what they paid?

The courts leave equally guilty parties where they stand

Article 1411 of the Civil Code states the consequence bluntly: where the nullity proceeds from the illegality of the cause or object and the act constitutes a criminal offence, both parties being in pari delicto, they shall have no action against each other, and both shall be prosecuted. The doctrine is not a reward for whoever happens to be holding the money. It is a refusal to lend the courts to either side of an unlawful bargain. The party who paid cannot recover; the party who took cannot be made to perform. Both are simply denied a remedy.

This is the trap in relying on nullity

People often reach for the argument that a contract was illegal, expecting that establishing it will get their money back. Under this article it frequently does the opposite. Proving the illegality proves your own participation in it, and the same finding that destroys the contract destroys your claim to restitution. Worse, the provision contemplates prosecution of both parties, and adds that the rules of the Penal Code on the disposal of the effects or instruments of a crime apply to the things or the price. So the money may not go back to anyone at all.

The innocent party is treated differently

The article's final sentence is the escape: This rule shall be applicable when only one of the parties is guilty; but the innocent one may claim what he has given, and shall not be bound to comply with his promise. Where one side genuinely did not know of and did not participate in the illegality, he keeps both rights — recovery of what he parted with, and release from his own undertaking. Everything therefore turns on whether the party seeking relief was truly innocent, which is a question of what he knew and when, not of how the arrangement was documented.

Where the unlawful act is not a crime

Article 1411 governs the case where the act is a criminal offence. Article 1412 deals with unlawful causes that fall short of a crime, and it follows the same logic with more room to move: where both are at fault neither may recover nor demand performance of the other's undertaking, while a party not at fault may demand the return of what he has given and is not bound to comply with his promise. The structure is consistent across both. Fault, not who currently holds the property, is what decides the outcome.
